推荐答案

试试这样..

try like this..

HiddenFieldControlName.Value=  dt.Rows[0]["columnName"].ToString();

试试这个

Try this

string[] arrayVariable= _dtblanck.AsEnumerable().Select(s => s.Field<string>("LoginName")).ToArray<string>();

现在你有了数组中列的值将执行您想要执行的任何操作。

Now you have all values of your column in an array do whatever you want to do with it.
