Append(StringBuilder)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Appends the string representation of a specified string builder to this instance.

public:
 System::Text::StringBuilder ^ Append(System::Text::StringBuilder ^ value);

public System.Text.StringBuilder Append (System.Text.StringBuilder? value);

public System.Text.StringBuilder Append (System.Text.StringBuilder value);

member this.Append : System.Text.StringBuilder -> System.Text.StringBuilder

Public Function Append (value As StringBuilder) As StringBuilder

Parameters

value: StringBuilder

The string builder to append.

Returns

StringBuilder

A reference to this instance after the append operation is completed.

Applies to

Append(StringBuilder+AppendInterpolatedStringHandler)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Appends the specified interpolated string to this instance.

public:
 System::Text::StringBuilder ^ Append(System::Text::StringBuilder::AppendInterpolatedStringHandler % handler);

public System.Text.StringBuilder Append (ref System.Text.StringBuilder.AppendInterpolatedStringHandler handler);

member this.Append : AppendInterpolatedStringHandler -> System.Text.StringBuilder

Public Function Append (ByRef handler As StringBuilder.AppendInterpolatedStringHandler) As StringBuilder

Parameters

handler: StringBuilder.AppendInterpolatedStringHandler

The interpolated string to append.

Returns

StringBuilder

A reference to this instance after the append operation has completed.

Applies to

Append(UInt16)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Important

This API is not CLS-compliant.

Appends the string representation of a specified 16-bit unsigned integer to this instance.

public:
 System::Text::StringBuilder ^ Append(System::UInt16 value);

[System.CLSCompliant(false)]
public System.Text.StringBuilder Append (ushort value);

[<System.CLSCompliant(false)>]
member this.Append : uint16 -> System.Text.StringBuilder

Public Function Append (value As UShort) As StringBuilder

Parameters

value: UInt16

The value to append.

Returns

StringBuilder

A reference to this instance after the append operation has completed.

Attributes: CLSCompliantAttribute

Exceptions

ArgumentOutOfRangeException

Enlarging the value of this instance would exceed MaxCapacity.

Remarks

The Append(UInt16) method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.

System.Text.StringBuilder sb = new 
            System.Text.StringBuilder("The range of a 16-bit unsigned integer: ");
sb.Append(UInt16.MinValue).Append(" to ").Append(UInt16.MaxValue);
Console.WriteLine(sb);
// The example displays the following output:
//       The range of a 16-bit unsigned integer: 0 to 65535

let sb = StringBuilder "The range of a 16-bit unsigned integer: "
sb.Append(UInt16.MinValue).Append(" to ").Append UInt16.MaxValue |> ignore
printfn $"{sb}"
// The example displays the following output:
//       The range of a 16-bit unsigned integer: 0 to 65535

Dim sb As New System.Text.StringBuilder("The range of a 16-bit unsigned integer: ")
sb.Append(UInt16.MinValue).Append(" to ").Append(UInt16.MaxValue)
Console.WriteLine(sb)
' The example displays the following output:
'       The range of a 16-bit unsigned integer: 0 to 65535

The Append(UInt16) method calls the UInt16.ToString(IFormatProvider) method to get the string representation of value. To control the formatting of value, call the AppendFormat method.

The capacity of this instance is adjusted as needed.

Notes to Callers

In .NET Core and in the .NET Framework 4.0 and later versions, when you instantiate the StringBuilder object by calling the StringBuilder(Int32, Int32) constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the Append(String) and AppendFormat(String, Object) methods to append small strings.

The value to append.

Returns

Console.WriteLine(sb);
// The example displays the following output:

Console.WriteLine(sb)
' The example displays the following output:
'       The range of a 32-bit unsigned integer: 0 to 4294967295

The Append(UInt32) calls the UInt32.ToString method to get the string representation of value for the current culture. To control the formatting of value, call the AppendFormat method.

Remarks

The Append(Char, Int32) method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append('*', 5).AppendFormat("{0:C2}", value).Append('*', 5);

public System.Text.StringBuilder Append (ReadOnlySpan<char> value);

member this.Append : ReadOnlySpan<char> -> System.Text.StringBuilder

Public Function Append (value As ReadOnlySpan(Of Char)) As StringBuilder

Parameters

Important

This API is not CLS-compliant.

Appends the string representation of a specified 8-bit signed integer to this instance.

public System.Text.StringBuilder Append (sbyte value);

[<System.CLSCompliant(false)>]
member this.Append : sbyte -> System.Text.StringBuilder

Public Function Append (value As SByte) As StringBuilder

Parameters

value: SByte

The value to append.

Returns

StringBuilder

A reference to this instance after the append operation has completed.

Attributes: CLSCompliantAttribute

Exceptions

ArgumentOutOfRangeException

Enlarging the value of this instance would exceed MaxCapacity.

Remarks

The Append(SByte) method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.

System.Text.StringBuilder sb = new 
            System.Text.StringBuilder("The range of an 8-bit signed integer: ");
sb.Append(SByte.MinValue).Append(" to ").Append(SByte.MaxValue);
Console.WriteLine(sb);
// The example displays the following output:
//       The range of an 8-bit unsigned integer: -128 to 127

let sb = StringBuilder "The range of an 8-bit signed integer: "
sb.Append(SByte.MinValue).Append(" to ").Append SByte.MaxValue |> ignore
printfn $"{sb}"
// The example displays the following output:
//       The range of an 8-bit unsigned integer: -128 to 127

Dim sb As New System.Text.StringBuilder("The range of an 8-bit signed integer: ")
sb.Append(SByte.MinValue).Append(" to ").Append(SByte.MaxValue)
Console.WriteLine(sb)
' The example displays the following output:
'       The range of an 8-bit unsigned integer: -128 to 127

The Append(SByte) method calls the SByte.ToString(IFormatProvider) method to get the string representation of value for the current culture. To control the formatting of value, call the AppendFormat method.
