名稱 Description

初始化一個使用預設 tab 字串的新類別實例 HtmlTextWriter 。
HtmlTextWriter(TextWriter, String)

初始化一個新的類別實例 HtmlTextWriter ，並使用指定的制表字串字元。

HtmlTextWriter(TextWriter)

初始化一個使用預設 tab 字串的新類別實例 HtmlTextWriter 。

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

就是 TextWriter 渲染標記內容的實例。

範例

以下程式碼範例示範如何使用HtmlTextWriter(TextWriter)建構子建立名為 HtmlTextWriter的自訂StyledLabelHtmlWriter物件。 當 MyPage 客戶端瀏覽器請求從該 Page 類別衍生出的自訂類別時，瀏覽器會利用該 StyledLabelHtmlWriter 類別將其內容渲染到輸出串流中。

// 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

HtmlTextWriter當需要縮排某行時，建構子的HtmlTextWriter(TextWriter)超載會使用常數值DefaultTabString。 它呼叫 HtmlTextWriter(TextWriter, String) 過載來初始化新實例。

HtmlTextWriter(TextWriter, String)

初始化一個新的類別實例 HtmlTextWriter ，並使用指定的制表字串字元。

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

那 TextWriter 就是渲染標記內容的。

tabString
String

用來渲染行條縮排的字串。

備註

HtmlTextWriter當需要縮排某行時，建構子的超載HtmlTextWriter(TextWriter, String)會使用tabString。 它呼叫 TextWriter.TextWriter(IFormatProvider) 基礎建構子來初始化新實例。
