c# - 在 RichTextBox 中居中对齐段落

Question

我使用 RichTextBox，并且我想格式化段落中的所有行以对齐对齐，除了最后一行将对齐到中心。

像这样：

      sssssssssssssssssssssssss
      sssssssssssssssssssssssss
      sssssssssssssssssssssssss
           ssssssssssssss     

我使用此代码来证明对齐。

Answer 1

What you want is "center justify". Modify the enum, it's #5 below:

/// <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
}

Sample code:

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);
}

Answer 2

<RichTextBox>
            <FlowDocument>
                <Paragraph TextAlignment="Justify">
                    sssssssssssssssssssssssss
                    sssssssssssssssssssssssss
                    sssssssssssssssssssssssss
                </Paragraph>
                <Paragraph TextAlignment="Center">
                    sssssssssssssssssssssssss
                </Paragraph>
            </FlowDocument>
</RichTextBox>

主要使用段落 TextAlignment 会给你对齐文本的选项：1. 对齐，2. 居中，3. 左，4. 右；
