Insert(Int32, SByte)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Important

This API is not CLS-compliant.

Inserts the string representation of a specified 8-bit signed integer into this instance at the specified character position.

public:
 System::Text::StringBuilder ^ Insert(int index, System::SByte value);

[System.CLSCompliant(false)]
public System.Text.StringBuilder Insert (int index, sbyte value);

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

Public Function Insert (index As Integer, value As SByte) As StringBuilder

Parameters

index: Int32

The position in this instance where insertion begins.

value: SByte

The value to insert.

Returns

StringBuilder

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

Attributes: CLSCompliantAttribute

Exceptions

ArgumentOutOfRangeException

index is less than zero or greater than the length of this instance.

OutOfMemoryException

Enlarging the value of this instance would exceed MaxCapacity.

Remarks

SByte.ToString is used to get a string representation of value. Existing characters are shifted to make room for the new text. The capacity is adjusted as needed.

Notes to Callers

In the .NET Framework 3.5 Service Pack 1 and earlier versions, calls to this method threw an ArgumentOutOfRangeException if inserting value would cause the object's total length to exceed MaxCapacity. Starting with the .NET Framework 4, the method throws an OutOfMemoryException.

Applies to

Insert(Int32, Char[], Int32, Int32)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Inserts the string representation of a specified subarray of Unicode characters into this instance at the specified character position.

public:
 System::Text::StringBuilder ^ Insert(int index, cli::array <char> ^ value, int startIndex, int charCount);

public System.Text.StringBuilder Insert (int index, char[] value, int startIndex, int charCount);

public System.Text.StringBuilder Insert (int index, char[]? value, int startIndex, int charCount);

member this.Insert : int * char[] * int * int -> System.Text.StringBuilder

Public Function Insert (index As Integer, value As Char(), startIndex As Integer, charCount As Integer) As StringBuilder

Parameters

index: Int32

The position in this instance where insertion begins.

value: Char[]

A character array.

startIndex: Int32

The starting index within value.

charCount: Int32

The number of characters to insert.

Returns

StringBuilder

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

Exceptions

ArgumentNullException

value is null, and startIndex and charCount are not zero.

ArgumentOutOfRangeException

index, startIndex, or charCount is less than zero.

-or-

index is greater than the length of this instance.

-or-

startIndex plus charCount is not a position within value.

-or-

Enlarging the value of this instance would exceed MaxCapacity.

Remarks

Existing characters are shifted to make room for the new text. The capacity of this instance is adjusted as needed.

Applies to

Insert(Int32, String, Int32)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

member this.Insert : int * string * int -> System.Text.StringBuilder

Public Function Insert (index As Integer, value As String, count As Integer) As StringBuilder

Parameters

index: Int32

The position in this instance where insertion begins.

value: String

The string to insert.

count: Int32

The number of times to insert value.

Returns

StringBuilder

A reference to this instance after insertion has completed.

Exceptions

ArgumentOutOfRangeException

index is less than zero or greater than the current length of this instance.

-or-

count is less than zero.

OutOfMemoryException

The current length of this StringBuilder object plus the length of value times count exceeds MaxCapacity.

Remarks

Existing characters are shifted to make room for the new text. The capacity of this instance is adjusted as needed.

This StringBuilder object is not changed if value is null, value is not null but its length is zero, or count is zero.
