但是我很确定它应该是KeyBoard_textBox.Text.Remove(g -1，1);

but i am pretty sure it should be KeyBoard_textBox.Text.Remove(g -1, 1);

您正在获取字符串的长度.现在，字符串是从0开始索引的，如果将g用作索引，则可能会导致您溢出异常.

You are getting the length of the string. Now strings are 0-indexed, if you'd put g as the index it would maybe ge you an overflow exception.
