XmlWriterSettings.IndentChars 屬性

定義

取得或設定縮排時使用的字元字串。 當 Indent 屬性設為 true 時會使用這項設定。

public:
 property System::String ^ IndentChars { System::String ^ get(); void set(System::String ^ value); };
public string IndentChars { get; set; }
member this.IndentChars : string with get, set
Public Property IndentChars As String

屬性值

縮排時使用的字元字串。 它可以設為任何字串值。 不過,若要確保有效的 XML,您應該只指定有效的空白字元 (例如,空格字元、定位字元、歸位字元或換行符號)。 預設值為兩個空格。

例外狀況

指派至 IndentChars 的值為 null

範例

下列範例會 XmlWriter 建立物件,該物件會使用 TAB 字元進行縮排。

using System;
using System.IO;
using System.Xml;
using System.Text;

public class Sample {

  public static void Main() {

    XmlWriter writer = null;

    try {

       // Create an XmlWriterSettings object with the correct options.
       XmlWriterSettings settings = new XmlWriterSettings();
       settings.Indent = true;
       settings.IndentChars = ("\t");
       settings.OmitXmlDeclaration = true;

       // Create the XmlWriter object and write some content.
       writer = XmlWriter.Create("data.xml", settings);
       writer.WriteStartElement("book");
       writer.WriteElementString("item", "tesing");
       writer.WriteEndElement();
    
       writer.Flush();
     }
     finally  {
        if (writer != null)
          writer.Close();
     }
  }
}
Imports System.IO
Imports System.Xml
Imports System.Text

Public Class Sample 

  Public Shared Sub Main() 
  
    Dim writer As XmlWriter = Nothing

    Try 

       ' Create an XmlWriterSettings object with the correct options. 
       Dim settings As XmlWriterSettings = New XmlWriterSettings()
       settings.Indent = true
       settings.IndentChars = (ControlChars.Tab)
       settings.OmitXmlDeclaration = true

       ' Create the XmlWriter object and write some content.
       writer = XmlWriter.Create("data.xml", settings)
       writer.WriteStartElement("book")
       writer.WriteElementString("item", "tesing")
       writer.WriteEndElement()
    
       writer.Flush()

      Finally
         If Not (writer Is Nothing) Then
            writer.Close()
         End If
      End Try

   End Sub 
End Class

備註

此屬性僅適用于 XmlWriter 輸出文字內容的實例,否則會忽略此設定。 如果縮排字元會導致不正確 XML,則會 XmlWriter 擲回例外狀況。
