c# - RichTextBox 中的居中对齐段落

Question

我使用 RichTextBox，并且我想将段落中的所有行格式化为两端对齐，除了最后一行将居中对齐。

像这样:

      sssssssssssssssssssssssss
      sssssssssssssssssssssssss
      sssssssssssssssssssssssss
           ssssssssssssss     

我使用 this code用于证明对齐。

你想要的是“居中对齐”。修改枚举，它是下面的#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
}

示例代码:

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);
}
