    You misunderstand the error.  The error means you are trying to pass 21 arguments to a method that does not have a definition with 21 parameters.


    public void MyMethod(int param0, int param1, int param2)
    MyMethod(0, 1, 2, 3)

    The C# programming guide covers the fundamentals and term definitions.

    You are passing either too many parameters to the method, or you are not passing enough parameters to the method.

    It could also be that you a looking at the wrong signature of the method too that can have multiple signatures implemented by overloads, which you should be able to see when you hover over a method with the mouse pointer when trying to code for the method's usage as Visual Stuido displays the overloads.

    Hi sathyaav

    According to the error code, you  haven't provide enough parameters for your method. Else if you want to set the length of parameter, you could use the size property of parameter s.Here is the code, I hope it could help you.

    static void CreateSqlParameterSize()
        string description = "12 foot scarf - multiple colors, one previous owner";
        SqlParameter parameter = new SqlParameter("Description", SqlDbType.VarChar);
        parameter.Direction = ParameterDirection.InputOutput;
        parameter.Size = description.Length;
        parameter.Value = description;

    Best Regards
