c# - Why can't I use format specifier on DataGrid Value? - 


string foo = selectedrow.cells["foo"].value.tostring("d5");

gives me error of 

no overload method 'tostring' takes 1 arguments

so had use 

string foo = selectedrow.cells["foo"].value.tostring().padleft(5,'0');

anyone can explain why?

datagridviewcell.value of type system.object. object.tostring() method not take arguments. therefore, cannot provide format specifier.
