Hi All,

I am using data filter from DataTable using Select method.In my case Column Header have a special character so in filter section comes error.

Here is my Code...

In this case its working fine..

string sCondition = string.Format("[{0}] = '{1}'", "Country Name", "India");
DataRow[ ] dr = dtData.Select(sCondition);

Problem is occured in this case...

string sCondition = string.Format("[{0}] = '{1}'", "Unit [in Cr]", "INR");
DataRow[ ] dr = dtData.Select(sCondition);

In this case Column Name have brace '[ ] ' so my filter condition is not working..
Exception thrown: "Cannot interpret token ']' at position 11"
Please any one suggest me how to filter this type of column using Select method.

Advance Thanks.... :(

Hi All,

Thanks Friends...

Now i am found out the solution..
Just add a slash ("\") in near to closing brace...

string sCondition = string.Format("[{0}] = '{1}'", "Unit [in Cr\]", "INR");
DataRow[ ] dr = dtData.Select(sCondition);

Yes, this is called an escape sequence. I really thought Hiren Solanki knew that!
