可能的重复：
RichTextBox C# 设置插入符位置 winforms

我正在开发一个正在阅读的项目来自终端（tn3270）界面，该界面的插入符位置列为 X，Y，我想将其传递到显示完整终端界面的 Richtextbox。我尝试通过多种方式在谷歌上查找，但我似乎只能找到如何获取 Richtextbox 中插入符的 x,y 位置。

我正在寻找一个可以的功能

private void SetCaretLocation(iX,iY);

：编辑：

    private void SetCaretPos(int iX,int iY)
    {
        int iLen = 0;
        int iRow = 0;
        foreach (string str in richTextBox1.lines)
        {
            iRow++;
            iLen += str.Length;
            if (iRow == iX)
                break;
        }
        iLen += iY;

        richTextBox1.SelectionStart = iLen;
    }

我似乎正在接近一些东西。但位置似乎不正确匹配。

RichTextBox C# Set caret location winforms

I am working on a project where I am reading from a terminal(tn3270) interface which has a caret postion listed as X,Y which I want to pass on to my richtextbox that is displaying the full terminal interface. I have tried looking on google multiple ways, but all I can seem to find is how to GET the x,y location of the caret in the richtextbox.

I am looking to have a function that can be

private void SetCaretLocation(iX,iY);

:EDIT:

    private void SetCaretPos(int iX,int iY)
    {
        int iLen = 0;
        int iRow = 0;
        foreach (string str in richTextBox1.lines)
        {
            iRow++;
            iLen += str.Length;
            if (iRow == iX)
                break;
        }
        iLen += iY;

        richTextBox1.SelectionStart = iLen;
    }

I seem to be getting some what close. But the position does not seem to match up correctly.

我不确定这是否应该如何完成，但有一种方法：

private void SetCaretPosition(int rows, int col)
{
    int curPos = 0;
    if (richTextBox1.Lines.Length >= rows)
    {    
        for (int i = 0; i < rows - 1; ++i)
        {
           curPos += richTextBox1.Lines[i].Length + 1; //add 1 for the newline character
        }
        richTextBox1.SelectionStart = curPos + col; 
    }
    else
        richTextBox1.SelectionStart = richTextBox1.TextLength;
    richTextBox1.ScrollToCaret();             
}

我没有意识到您还发布了编辑。您需要考虑新行字符。如果是 \n，则为 1；如果是 \r\n，则为 2

I am not sure if this is how it should be done but its 1 way:

private void SetCaretPosition(int rows, int col)
{
    int curPos = 0;
    if (richTextBox1.Lines.Length >= rows)
    {    
        for (int i = 0; i < rows - 1; ++i)
        {
           curPos += richTextBox1.Lines[i].Length + 1; //add 1 for the newline character
        }
        richTextBox1.SelectionStart = curPos + col; 
    }
    else
        richTextBox1.SelectionStart = richTextBox1.TextLength;
    richTextBox1.ScrollToCaret();             
}

Edit:

I didn't realize you had also posted an edit. You need to consider the new line character. 1 if its \n, 2 if its \r\n
