推荐答案

试试这样..

Try like this..

txtid.Text =dataGridView1.Rows[dataGridView1.Rows.Count -1 ].Cells[348].Value.ToString;

您正在使用dataGridView1.RowCount，它将返回总行数。现在，假设值348是正确的，请记住，在尝试从集合中获取值时，如下所示，其索引为零，可以按如下方式访问最后一个值：

You're using dataGridView1.RowCount which will return the total count of rows. Now, assuming that the value 348 is correct, always remember that while trying to fetch a value from a collection, like this, whose index are zero based, the last value can be accessed as follows:

txtid.Text =dataGridView1.Rows[(dataGridView1.RowCount  - 1)].Cells[348].Value.ToString;

对于收藏中的ex，长度为10的ABC，如果你写ABC [ABC.Length]，则意味着你想要访问不存在的集合的第11个索引，因此出现此错误。

For ex in a collection, ABC of length 10, if you write ABC[ABC.Length], it means you're tring to access the 11th index of the collection which is not there, hence this error.
