无法对System.String和System.Int32执行'='操作。

Hi
Actually i am using String Builder to Filter data, i have used various filters by using string builder, and at finally i used this:

dsDetails.Tables["CertificationDetails"].DefaultView.RowFilter = sbRowFilter.ToString();,

this is Giving Exception to me that :
Cannot perform '=' operation on System.String and System.Int32.

Please Help ME ASAP

if (DepartmentID > 0)
                     {
                         if (string.IsNullOrEmpty(sbRowFilter.ToString()))
                         {
                             sbRowFilter.Append("ISDepartmentMatch '=' 1");

                         }

                     }

此后我打电话：

dsDetails.Tables [CertificationDetails]。DefaultView.RowFilter = sbRowFilter.ToString（）;

After This i Called:
dsDetails.Tables["CertificationDetails"].DefaultView.RowFilter = sbRowFilter.ToString();

推荐答案

sbRowFilter.Append("ISDepartmentMatch= '1'");

该错误告诉您它无法将整数转换为字符串。在值周围放置单引号并删除等号周围的单引号。

The error is telling you that it can't convert an integer to string. Place single quotes around the value and remove the single quotes around the equal sign.

错误表示无法执行'='操作。您不应该使用单引号包装逻辑运算符=。从=运算符中删除引号，然后重试

The error says Cannot perform '=' operation. You should not wrap logical operator = with single quotes. Remove quotes from = operator and try again
