WriteLine(String, Object, Object)
- Source:
- TextWriter.cs

- TextWriter.cs
- Source:
- TextWriter.cs
Writes a formatted string and a new line to the text stream, using the same semantics as the Format(String, Object, Object) method.
public:
virtual void WriteLine(System::String ^ format, System::Object ^ arg0, System::Object ^ arg1);
public virtual void WriteLine (string format, object arg0, object arg1);
public virtual void WriteLine (string format, object? arg0, object? arg1);
abstract member WriteLine : string * obj * obj -> unit
override this.WriteLine : string * obj * obj -> unit
Public Overridable Sub WriteLine (format As String, arg0 As Object, arg1 As Object)
Parameters
- format
- String
A composite format string.
- arg0
- Object
The first object to format and write.
- arg1
- Object
The second object to format and write.
Exceptions
format
is null
.
The TextWriter is closed.
An I/O error occurs.
format
is not a valid composite format string.
-or-
The index of a format item is less than 0 (zero), or greater than or equal to the number of objects to be formatted (which, for this method overload, is two).
Remarks
This method uses composite formatting to convert the value of an object to its string representation and to embed that representation in a string. .NET provides extensive formatting support, which is described in greater detail in the following formatting topics:
For more information about the composite formatting feature, see Composite Formatting.
For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about date and time format specifiers, see Standard Date and Time Format Strings and Custom Date and Time Format Strings.
For more information about enumeration format specifiers, see Enumeration Format Strings.
For more information about formatting, see Formatting Types.
The format
parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. The formatting process replaces each format item with the string representation of the value of the corresponding object.
The syntax of a format item is as follows:
{index[,length][:formatString]}
Elements in square brackets are optional. The following table describes each element. For more information about the composite formatting feature, including the syntax of a format item, see Composite Formatting.
Element | Description |
---|---|
index | The zero-based position in the parameter list of the object to be formatted. If the object specified by index is null , the format item is replaced by String.Empty. Because this overload has two objects in its parameter list, the value of index must always be 0 or 1. If there is no parameter in the index position, a FormatException is thrown. |
,length | The minimum number of characters in the string representation of the parameter. If positive, the parameter is right-aligned; if negative, it is left-aligned. |
:formatString | A standard or custom format string that is supported by the object to be formatted. Possible values for formatString are the same as the values supported by the object's ToString(string format) method. If formatString is not specified and the object to be formatted implements the IFormattable interface, null is passed as the value of the format parameter that is used as the IFormattable.ToString format string. |
The leading and trailing brace characters, "{" and "}", are required. To specify a single literal brace character in format
, specify two leading or trailing brace characters; that is, "{{" or "}}".
This method does not search the specified string for individual newline characters (hexadecimal 0x000a) and replace them with NewLine.
If a specified object is not referenced in the format string, it is ignored.
The line terminator is defined by the CoreNewLine field.

Public Overridable Sub WriteLine (buffer As Char(), index As Integer, count As Integer)
Parameters
- buffer
- Char[]
The character array from which data is read.
- index
- Int32
The character position in buffer
at which to start reading data.
- count

Exceptions
The buffer length minus index
is less than count
.
The buffer
parameter is null
.
index
or count
is negative.
The TextWriter is closed.
An I/O error occurs.
Remarks
This method will write count
characters of data into this TextWriter
from the buffer
character array starting at position index
.
This overload is equivalent to calling the Write(Char[]) method followed by WriteLine for each character in buffer
between index
and (index
+ count
).
The line terminator is defined by the CoreNewLine field.

WriteLine(Decimal)
- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
Writes the text representation of a decimal value to the text stream, followed by a line terminator.
public:
virtual void WriteLine(System::Decimal value);
public virtual void WriteLine (decimal value);
abstract member WriteLine : decimal -> unit
override this.WriteLine : decimal -> unit
Public Overridable Sub WriteLine (value As Decimal)
Parameters
- value
- Decimal
The decimal value to write.
Exceptions
The TextWriter is closed.
An I/O error occurs.
Remarks
The FormatProvider property, if not null
, specifies the culture-specific formatting. For a list of common I/O tasks, see Common I/O Tasks.
The line terminator is defined by the CoreNewLine field.

WriteLine(Char[])
- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
Writes an array of characters to the text stream, followed by a line terminator.
public:
virtual void WriteLine(cli::array <char> ^ buffer);
public virtual void WriteLine (char[] buffer);
public virtual void WriteLine (char[]? buffer);
abstract member WriteLine : char[] -> unit
override this.WriteLine : char[] -> unit
Public Overridable Sub WriteLine (buffer As Char())
Parameters
- buffer
- Char[]
The character array from which data is read.
Exceptions
The TextWriter is closed.
An I/O error occurs.
Remarks
All the characters in buffer
are written to the underlying stream. If the character array is null
, only the line terminator is written.
This overload is equivalent to Write(Char[]) followed by WriteLine() .
The line terminator is defined by the CoreNewLine field.

- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
- Source:
- TextWriter.cs
Writes the text representation of a Boolean
value to the text stream, followed by a line terminator.
public:
virtual void WriteLine(bool value);
public virtual void WriteLine (bool value);
abstract member WriteLine : bool -> unit
override this.WriteLine : bool -> unit
Public Overridable Sub WriteLine (value As Boolean)
Parameters
- value
- Boolean
The Boolean
value to write.
Exceptions
The TextWriter is closed.
An I/O error occurs.
Remarks
The text representation of the specified value is produced by calling the Boolean.ToString method.
This method outputs either Boolean.TrueString or Boolean.FalseString.
The line terminator is defined by the CoreNewLine field.
