推荐答案

对于DataTable类的Select方法，在FilterExpression条件下的Text应该用单引号引起来.因此，将单引号放在select方法中，如下所示

For the Select method of DataTable class, the Text in the condition of FilterExpression shall be enclosed in single quotes. Hence, put single quotes in the select method as shown below

rec = ds.Tables[0].Select("Enm.Id='" + txtemp.Text  + "'")[0];
