Question

I have a problem with the var keyword

I have defined it like this at the form load

public partial class form1 :form
{
    public var a;


    private void form1_load(object sender, eventargs e)
    {
        // i have used "a" like this....
        a = abc.members blahhhh blahhhhh
        bindingsource1.datasource = a;
        datagridview1.datasource = bindingsource1;

    }
}

but I got the error on this line

public Var a;

the type or namespace name ‘var’ could not be defined

Can I define public class varaible so that I can access this all methods in that class?

Answer 1

var in C# is different from var in other languages; in C# you use var to have the compiler determine the type of a certain local variable for you, but you cannot use it to declare fields/properties.

You have to specify the actual type instead. I have no idea what a is, so I can’t tell you what type to use.
