命名空間:

System.Web.UI

組件:

System.Web.dll

多載

HtmlTextWriter(TextWriter)	初始化 HtmlTextWriter 類別的新執行個體 (此執行個體使用預設的定位字串)。
HtmlTextWriter(TextWriter, String)	使用指定的定位字串字元初始化 HtmlTextWriter 類別的新執行個體。

HtmlTextWriter(TextWriter)

初始化 HtmlTextWriter 類別的新執行個體 (此執行個體使用預設的定位字串)。

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

public HtmlTextWriter (System.IO.TextWriter writer);

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

Public Sub New (writer As TextWriter)

參數

writer

TextWriter

呈現標記內容的 TextWriter 執行個體。

範例

下列程式碼範例示範如何使用 建 HtmlTextWriter(TextWriter) 構函式來建立名為 的 StyledLabelHtmlWriter 自訂 HtmlTextWriter 物件。 MyPage當用戶端瀏覽器要求衍生自 類別的 Page 自訂類別時，它會使用 StyledLabelHtmlWriter 類別將內容轉譯至輸出資料流程。

// A custom class that overrides its CreateHtmlTextWriter method.
// This page uses the StyledLabelHtmlWriter class to render its content.
public ref class MyPage: public Page
{
protected:
   virtual HtmlTextWriter^ CreateHtmlTextWriter( TextWriter^ writer ) override
   {
      return gcnew HtmlStyledLabelWriter( writer );
   }
};

// A custom class that overrides its CreateHtmlTextWriter method.
// This page uses the HtmlStyledLabelWriter class to render its content.
[AspNetHostingPermission(SecurityAction.Demand,
    Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(SecurityAction.InheritanceDemand,
    Level = AspNetHostingPermissionLevel.Minimal)]
public class MyPage : Page
{
    protected override HtmlTextWriter CreateHtmlTextWriter(TextWriter writer)
    {
        return new HtmlStyledLabelWriter(writer);
    }
}

' A custom class that overrides the CreateHtmlTextWriter method.
' This page uses the StyledLabelHtmlWriter to render its content.  
<AspNetHostingPermission(SecurityAction.Demand, _
    Level:=AspNetHostingPermissionLevel.Minimal)> _
<AspNetHostingPermission(SecurityAction.InheritanceDemand, _
    Level:=AspNetHostingPermissionLevel.Minimal)> _
Public Class MyPage
    Inherits Page

    Protected Overrides Function CreateHtmlTextWriter(ByVal writer As TextWriter) As HtmlTextWriter
        Return New HtmlStyledLabelWriter(writer)
    End Function 'CreateHtmlTextWriter
End Class

備註

需要行縮排時， DefaultTabString 建 HtmlTextWriter 構函式的多 HtmlTextWriter(TextWriter) 載會使用常數。 它會呼叫 HtmlTextWriter(TextWriter, String) 多載來初始化新的實例。

HtmlTextWriter(TextWriter, String)

使用指定的定位字串字元初始化 HtmlTextWriter 類別的新執行個體。

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

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

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

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

參數

writer

TextWriter

呈現標記內容的 TextWriter。

tabString

String

用來呈現行縮排的字串。

備註

HtmlTextWriter建構函式的多 HtmlTextWriter(TextWriter, String) 載會在需要行縮排時使用 tabString 。 它會呼叫基底建 TextWriter.TextWriter(IFormatProvider) 構函式來初始化新的實例。
