  • Simple.  Make change like this

    from : int a;

    to : int a = 0;

  • Hi, 

    Reason for this , You have defined a variable but never was declared or assigned (here)

    This could be because of designer.cs issues, this can be solved close VS and open and rebuild. If not please provide the lines of code.

  • Hi fabrivera,

    This is the issue with designer.cs. Probably you have declared a control, but forgt to initialize it,

    For exmple: you might have declared a label but forgot to do new for that as

    myLabel=new Label();

    Please check your code once. Sometimes, these things occur, on corruption of designer.
