WriteLine(String, Object, Object)

Writes any pending tab spacing and a formatted string that contains the text representation of two objects, followed by a line terminator string, to the output stream.

public:
 override void WriteLine(System::String ^ format, System::Object ^ arg0, System::Object ^ arg1);

public override void WriteLine (string format, object arg0, object arg1);

override this.WriteLine : string * obj * obj -> unit

Public Overrides Sub WriteLine (format As String, arg0 As Object, arg1 As Object)

Parameters

format: String

A string containing zero or more format items.

arg0: Object

An object to format.

arg1: Object

An object to format.

Examples

The following code example demonstrates how to use the WriteLine method to render a formatted string and the values of the CurrentCulture property and the Today property.

// Use the WriteLine(string,object,object) method to
// render a formatted string and two objects 
// in the string.
writer.RenderBeginTag(HtmlTextWriterTag.Label);
writer.WriteLine("The current cultural settings are {0}. Today's date is {1}.",
    CultureInfo.CurrentCulture, DateTime.Today);
writer.RenderEndTag();

' Use the WriteLine(string,object,object) method to
' render a formatted string and two objects 
' in the string.
writer.RenderBeginTag(HtmlTextWriterTag.Label)
writer.WriteLine("The current cultural settings are {0}. Today's date is {1}.", _
    CultureInfo.CurrentCulture, DateTime.Today)
writer.RenderEndTag()

Remarks

The default line terminator string is a carriage return followed by a line feed ("\r\n"). The WriteLine method uses the same semantics as the Format(String, Object, Object) method. The WriteLine base method is used to write the value parameter.

Applies to

WriteLine(Char[], Int32, Int32)

Writes any pending tab spacing and a subarray of Unicode characters, followed by a line terminator string, to the output stream.

public:
 override void WriteLine(cli::array <char> ^ buffer, int index, int count);

public override void WriteLine (char[] buffer, int index, int count);

override this.WriteLine : char[] * int * int -> unit

Public Overrides Sub WriteLine (buffer As Char(), index As Integer, count As Integer)

Parameters

buffer: Char[]

The character array from which to write text to the output stream.

index: Int32

The location in the character array where writing begins.

count: Int32

The number of characters in the array to write to the output stream.

Examples

This section contains two code examples. The first one demonstrates how to create a character array. The second one demonstrates how to use the array.

These code examples generate the following markup:

<label>

hello

</label>

The following code example demonstrates how to create an array of characters that spell out hello world. Included in the array is the SpaceChar field, which creates a space between the two words.

private char[] testChars = {'h', 'e', 'l', 'l', 'o',
    HtmlTextWriter.SpaceChar ,'w', 'o', 'r', 'l', 'd'};

Private testChars() As Char = _
    {"h"c, "e"c, "l"c, "l"c, "o"c, _
    HtmlTextWriter.SpaceChar, "w"c, "o"c, "r"c, "l"c, "d"c}

The following code example uses the index and count parameters of the WriteLine method to render the first five characters of the array created in the preceding code example.

// Render a subarray of a character array
// as the contents of a <label> element.
writer.RenderBeginTag(HtmlTextWriterTag.Label);
writer.WriteLine(testChars, 0, 5);
writer.RenderEndTag();

' Render a subarray of a character array
' as the contents of a <label> element.
writer.RenderBeginTag(HtmlTextWriterTag.Label)
writer.WriteLine(testChars, 0, 5)
writer.RenderEndTag()

Remarks

The default line terminator string is a carriage return followed by a line feed ("\r\n"). The WriteLine base method is used to write the value parameter.

Applies to

WriteLine(String, Object[])

Writes any pending tab spacing and a formatted string that contains the text representation of an object array, followed by a line terminator string, to the output stream.

public:
 override void WriteLine(System::String ^ format, ... cli::array <System::Object ^> ^ arg);

public override void WriteLine (string format, params object[] arg);

override this.WriteLine : string * obj[] -> unit

Public Overrides Sub WriteLine (format As String, ParamArray arg As Object())

Parameters

format: String

A string containing zero or more format items.

arg: Object[]

An object array to format.

Examples

This section contains two code examples. The first one demonstrates how to render a string and an array to the output stream. The second one shows how to declare the array.

The following code example demonstrates how to use the WriteLine method to render a formatted string and the contents of an object array to the output stream.

// Render a formatted string and the
// text representation of an object array,
// myObjectArray, as the contents of
// a <label> element.
writer.RenderBeginTag(HtmlTextWriterTag.Label);
writer.WriteLine("The trade value at {1} is ${0}.", curPriceTime);
writer.RenderEndTag();

' Render a formatted string and the
' text representation of an object array,
' myObjectArray, as the contents of
' a <label> element.
writer.RenderBeginTag(HtmlTextWriterTag.Label)
writer.WriteLine("The trade value at {1} is ${0}.", curPriceTime)
writer.RenderEndTag()

The following code example shows how to declare the object array that was rendered in the preceding code example.

private object[] curPriceTime = {4.25, DateTime.Now};

Private curPriceTime() As Object = {4.25, DateTime.Now}

Remarks

The default line terminator string is a carriage return followed by a line feed ("\r\n"). The WriteLine method uses the same semantics as the Format(String, Object[]) method. The WriteLine base method is used to write the value method.

Applies to

public:
 override void WriteLine(System::String ^ format, System::Object ^ arg0);

The following code example shows how to use the WriteLine method to render a formatted string with the value of the CurrentCulture property.

// Use the WriteLine(string, object) method to
// render a formatted string and an object in it.
writer.RenderBeginTag(HtmlTextWriterTag.Label);
writer.WriteLine("The current cultural settings are {0}",
    CultureInfo.CurrentCulture);
writer.RenderEndTag();

' Use the WriteLine(string, object) method to
' render a formatted string and an object in it.
writer.RenderBeginTag(HtmlTextWriterTag.Label)
writer.WriteLine("The current cultural settings are {0}.", _
    CultureInfo.CurrentCulture)
writer.RenderEndTag()

Remarks

The default line terminator string is a carriage return followed by a line feed ("\r\n"). The WriteLine method uses the same semantics as the Format(String, Object) method. The WriteLine base method is used to write the value parameter.
