XhtmlTextWriter Constructors

Definition

Namespace:

System.Web.UI

Assembly:

System.Web.dll

Initializes a new instance of the XhtmlTextWriter class.

Overloads

XhtmlTextWriter(TextWriter)	Initializes a new instance of the XhtmlTextWriter class that uses the line indentation that is specified in the DefaultTabString field. Use the XhtmlTextWriter(TextWriter) constructor if you do not want to change the default line indentation.
XhtmlTextWriter(TextWriter, String)	Initializes a new instance of the XhtmlTextWriter class with the specified line indentation.

XhtmlTextWriter(TextWriter)

Initializes a new instance of the XhtmlTextWriter class that uses the line indentation that is specified in the DefaultTabString field. Use the XhtmlTextWriter(TextWriter) constructor if you do not want to change the default line indentation.

public:
 XhtmlTextWriter(System::IO::TextWriter ^ writer);

public XhtmlTextWriter (System.IO.TextWriter writer);

new System.Web.UI.XhtmlTextWriter : System.IO.TextWriter -> System.Web.UI.XhtmlTextWriter

Public Sub New (writer As TextWriter)

Parameters

writer

TextWriter

A TextWriter instance that renders the XHTML content.

Examples

The following code example demonstrates how to create the two constructors, which is standard for all classes that derive directly or indirectly from the HtmlTextWriter class, for a custom class that is derived from the XhtmlTextWriter class.

// Create a class that inherits from XhtmlTextWriter.
[AspNetHostingPermission(SecurityAction.Demand, 
    Level=AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(SecurityAction.InheritanceDemand, 
    Level=AspNetHostingPermissionLevel.Minimal)] 
public class CustomXhtmlTextWriter : XhtmlTextWriter
{
    // Create two constructors, following 
    // the pattern for implementing a
    // TextWriter constructor.
    public CustomXhtmlTextWriter(TextWriter writer) : 
        this(writer, DefaultTabString)
    {
    }

    public CustomXhtmlTextWriter(TextWriter writer, string tabString) : 
        base(writer, tabString)
    {
    }

' Create a class that inherits from XhtmlTextWriter.
<AspNetHostingPermission(SecurityAction.Demand, _
    Level:=AspNetHostingPermissionLevel.Minimal)> _
<AspNetHostingPermission(SecurityAction.InheritanceDemand, _
    Level:=AspNetHostingPermissionLevel.Minimal)> _
Public Class CustomXhtmlTextWriter
    Inherits XhtmlTextWriter

    ' Create two constructors, following 
    ' the pattern for implementing a
    ' TextWriter constructor.
    Public Sub New(writer As TextWriter)
      MyClass.New(writer, DefaultTabString)
    End Sub


    Public Sub New(writer As TextWriter, tabString As String)
      MyBase.New(writer, tabString)
    End Sub

Remarks

The XhtmlTextWriter constructor that takes a TextWriter object as a parameter calls the second constructor, passing two parameter values:

• The TextWriter instance.

• The string value that is specified in the DefaultTabString field, which defines the tab spacing that is used by the XHTML text writer.

XhtmlTextWriter(TextWriter, String)

Initializes a new instance of the XhtmlTextWriter class with the specified line indentation.

public:
 XhtmlTextWriter(System::IO::TextWriter ^ writer, System::String ^ tabString);

public XhtmlTextWriter (System.IO.TextWriter writer, string tabString);

new System.Web.UI.XhtmlTextWriter : System.IO.TextWriter * string -> System.Web.UI.XhtmlTextWriter

Public Sub New (writer As TextWriter, tabString As String)

Parameters

writer

TextWriter

A TextWriter instance that renders the XHTML content.

tabString

String

The string used to render a line indentation.
