Bhushan Bhasme · Answer

this error mostly occur due to missing referenceextra or less }. so public class DBdata { } .you need to close it at the bottom of code not there itself.(i.e: after closing ofbelow method public DataSet SelectAllDatabyID(string MobileID) { } ) something like this.. namespace xyz { public class DBdata { public DataSet SelectAllDatabyID(string MobileID) { //Your Code } }//end of class } //end of namespace like this hope this will help You
