推荐答案

1. 在文本框中获取插入符号的索引:

1. Get the index of the caret in the TextBox:

C#

int caretIndex = textBox.SelectionStart;

VB.NET

Dim caretIndex As Integer = textBox.SelectionStart

从插入号索引中获取行号:

Get the line number from the caret index:

C#

int lineNumber = textBox.GetLineFromCharIndex(caretIndex);

VB.NET

Dim lineNumber As Integer = textBox.GetLineFromCharIndex(caretIndex)

获取当前行中的字符索引:

Get the character index in the current line:

C#

Point characterXY = textBox.GetPositionFromCharIndex(caretIndex);
int characterIndex = textBox.GetCharIndexFromPosition(characterXY);

VB.NET

Dim characterXY As Point = textBox.GetPositionFromCharIndex(caretIndex)
Dim characterIndex As Integer = textBox.GetCharIndexFromPosition(characterXY)
