您好!您提到的问题是关于WPF RichTextBox用行号创建编辑器。以下是我的回答:
WPF RichTextBox是Windows Presentation Foundation中的一个控件,它可以显示和编辑富文本内容,包括文本、图像、表格等。要在RichTextBox中添加行号,可以使用以下方法:
<RichTextBox x:Name="richTextBox" />
private void AddLineNumbers()
{
TextPointer insertionPosition = richTextBox.Document.ContentStart;
string text = richTextBox.Document.Blocks.FirstBlock.ToString();
string[] lines = text.Split('\n');
for (int i = 0; i< lines.Length; i++)
{
// 创建一个Run对象,用于显示行号
Run run = new Run((i + 1).ToString() + " ");
// 将行号Run对象添加到文档中
insertionPosition = richTextBox.Document.ContentStart.InsertLineBreak();
insertionPosition.InsertTextInRun(" ");
insertionPosition.InsertTextInRun(" ");
insertionPosition.InsertTextInRun(" ");
insertionPosition.InsertTextInRun(" ");
