推荐答案

DataGridViewCell的对象有值方法，它返回callvalue为对象，就可以转换为字符串值，然后核对这个字符串null或空。

DataGridViewCell object has "Value" method which returns callvalue as object, That value you can convert to string then check this string against null or empty.

string val = this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value as string;
if(string.isNullorEmpty(val) ==false)
{
  // your method run.
}
