XhtmlTextWriter 构造函数

定义

命名空间:

System.Web.UI

程序集:

System.Web.dll

初始化 XhtmlTextWriter 类的新实例。

重载

XhtmlTextWriter(TextWriter)	初始化 XhtmlTextWriter 类的新实例，该类使用在 DefaultTabString 字段中指定的行缩进。 如果不希望更改默认行缩进，请使用 XhtmlTextWriter(TextWriter) 构造函数。
XhtmlTextWriter(TextWriter, String)	使用指定的行缩进初始化 XhtmlTextWriter 类的新实例。

XhtmlTextWriter(TextWriter)

初始化 XhtmlTextWriter 类的新实例，该类使用在 DefaultTabString 字段中指定的行缩进。 如果不希望更改默认行缩进，请使用 XhtmlTextWriter(TextWriter) 构造函数。

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)

参数

writer

TextWriter

呈现 XHTML 内容的 TextWriter 实例。

示例

下面的代码示例演示如何为派生自 类的自定义类创建两个构造函数，这是直接或间接派生自 HtmlTextWriter 类的所有类的标准 XhtmlTextWriter 构造函数。

// 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

注解

采用 XhtmlTextWriter 对象作为参数的构造函数调用第二个构造函数，传递两个 TextWriter 参数值：

• TextWriter 实例。

• 字段中 DefaultTabString 指定的字符串值，用于定义 XHTML 文本编写器使用的制表符间距。

XhtmlTextWriter(TextWriter, String)

使用指定的行缩进初始化 XhtmlTextWriter 类的新实例。

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)

参数

writer

TextWriter

呈现 XHTML 内容的 TextWriter 实例。

tabString

String

用于呈现行缩进的字符串。
