“ Operator Name”运算符后缺少操作数

Question

I am filtering my gridview using dataview. I am passing the filter command to dataview as mentioned below;

string strFilter= " 0=0 ";

if (Session["SampleSession"] != null)
        {
            strFilter= strFilter+ " and Emp Name = '" + Session["SampleSession"].ToString() + "' ";
        }
dv.RowFilter = strFilter;  // Throws an error here!

It throws an error of Missing operand after 'Operator Name' operator in above line.

i believe there is small error which i am unable to catch.

您的问题是“ Emp名称”（列名称）包含一个空格，需要在过滤器表达式中用方括号括起来：

strFilter= strFilter+ " and [Emp Name] = '" + Session["SampleSession"].ToString() + "' ";
