RichTextBox中的中心對齊段落

Question

我使用RichTextBox，我想用對齊方式對齊段落中的所有行，但最後一行將對齊中心。

就象這樣：

 sssssssssssssssssssssssss 
     sssssssssssssssssssssssss 
     sssssssssssssssssssssssss 
      ssssssssssssss  

我用this code爲兩端對齊。

你想要的是「中心證明」。修改枚舉，這是低於5：

/// <summary> 
/// Specifies how text in a <see cref="AdvRichTextBox"/> is 
/// horizontally aligned. 
/// </summary> 
public enum TextAlign 
{ 
    /// <summary> 
    /// The text is aligned to the left. 
    /// </summary> 
    Left = 1, 

    /// <summary> 
    /// The text is aligned to the right. 
    /// </summary> 
    Right = 2, 

    /// <summary> 
    /// The text is aligned in the center. 
    /// </summary> 
    Center = 3, 

    /// <summary> 
    /// The text is justified. 
    /// </summary> 
    Justify = 4, 

    /// <summary> 
    /// The text is center justified. 
    /// </summary> 
    CenterJustify = 5 
} 

示例代碼：

private void Form1_Load(object sender, EventArgs e) 
{ 
    AdvRichTextBox tb = new AdvRichTextBox(); 

    tb.SelectionAlignment = TextAlign.CenterJustify; 
    tb.SelectedText = "Here is a justified paragraph. It will show up justified using the new AdvRichTextBox control created by who knows.\n"; 

    tb.Width = 250; 
    tb.Height = 450; 

    this.Controls.Add(tb); 
}
