你可以使用< a href =https://msdn.microsoft.com/en-us/library/system.windows.controls.richtextbox.caretposition(v=vs.110).aspx> RichTextBox.CaretPosition [ ^ ]属性，用于访问内容中插入符号的当前索引。



以下代码是从MSDN捕获的，

You can use RichTextBox.CaretPosition[^] property to access the current index of caret inside the content.

Following code was captured from MSDN,

// Create a new FlowDocument, and add 3 paragraphs.
FlowDocument flowDoc = new FlowDocument();
flowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 1"))); 
flowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 2"))); 
flowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 3")));
// Set the FlowDocument to be the content for a new RichTextBox.
RichTextBox rtb = new RichTextBox(flowDoc);

// Get the current caret position.
TextPointer caretPos = rtb.CaretPosition;

// Set the TextPointer to the end of the current document.
caretPos = caretPos.DocumentEnd;

// Specify the new caret position at the end of the current document.
rtb.CaretPosition = caretPos;

您可以看到这些是如何操作文档中的插入位置的一些方法，你可以得到位置，以及设置位置。

You can see that these are a few of the methods how you can manipulate the caret position inside the document, you can get the position, as well as set the position.
