Compiler Error CS0305 Other Versions Visual Studio 2008 Visual Studio 2005 Using the generic type 'generic type' requires 'number' type argumentsThis error occurs when the expected number of type arguments was not found. To resolve C0305, use the required number of type arguments.ExampleThe following sample generates CS0305. Copy // CS0305.cs public class MyList {} public class MyClass {} class MyClass { public static void Main() { MyList list1 = new MyList(); // CS0305 MyList list2 = new MyList(); // OK } } Show: Inherited Protected Print Export (0) Print Export (0) Share IN THIS ARTICLE Is this page helpful?

Any ideas how to solve this? Thanks. edit: The call looks like this: /// Inverse cumulative distribution function /// Probabilities at which to compute the inverse cdf /// Scale parameters public static IDoubleArray Inv(IDoubleArray p, IDoubleArray mu) { return ArrayMath.ApplyFunc(Matrix.ConvertToMatrix(p), Matrix.ConvertToMatrix(mu), Inv); } c# delegates share|improve this question edited Apr 15 '11 at 9:23 asked Apr 15 '11 at 9:14 Klark 5,08932347 What's the call to ApplyFunc look like –Preet Sangha Apr 15 '11 at 9:17 are you sure the error message is not The best overloaded method match for '...ApplyFunc(IDoubleArray, IDoubleArray, System.Func)' has some invalid arguments... ? –manji Apr 15 '11 at 9:27 Well yes, I am sure :D –Klark Apr 15 '11 at 9:28 because Inv function you're passing to ApplyFunc has a signature = (IDoubleArray, IDoubleArray, IDoubleArray) and ApplyFunc needs (double, double, double) or am I off track? –manji Apr 15 '11 at 9:30 ApplyFunc has signature (IDoubleArray, IDoubleArray, Func). There is another Inv function with signature (double, double). But that is not the problem. The error is generated at the ApplyF
