问题描述

你好家伙



i我收到此错误



指数超出范围。必须是非负数且小于集合的大小。

参数名称：index

hello guys

i am getting this error

"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

private void ExcelDGV_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex != -1)
    {
        textBox1.Text = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
    }
}

任何帮助将不胜感激，谢谢

any help will be appreciated , thanks

推荐答案

这里有两种可能：

1）RowIndex超出范围，

2）单元格超出范围，



如果它不是RowIndex，那么它必须是Cell - 有没有？

或者...应该是dataGridView1在哪？方法名称暗示控件名为ExcelDGV ...



使用调试器查看行的各个部分，看看你有什么。

Two possibilities here:
1) RowIndex is out of the range,
2) Cells is out of the range,

If it isn't the RowIndex, then it has to be the Cells - are there any?
Or...should that be dataGridView1 at all? The method name implies the control is called ExcelDGV...

Use the debugger to look at the parts of the line and see what you do have.
