示例2: CheckConstraint

		static bool CheckConstraint (IMemberContext mc, MemberSpec context, TypeSpec atype, TypeParameterSpec tparam, Location loc)
		{
			//
			// First, check the `class' and `struct' constraints.
			//

					"The type `{0}' must be a reference type in order to use it as type parameter `{1}' in the generic type or method `{2}'",
					TypeManager.CSharpName (atype), tparam.GetSignatureForError (), context.GetSignatureForError ());
				return false;
			}

			if (tparam.HasSpecialStruct && (!TypeManager.IsValueType (atype) || TypeManager.IsNullableType (atype))) {
				mc.Compiler.Report.Error (453, loc,
					"The type `{0}' must be a non-nullable value type in order to use it as type parameter `{1}' in the generic type or method `{2}'",
					TypeManager.CSharpName (atype), tparam.GetSignatureForError (), context.GetSignatureForError ());
				return false;
			}

			//
			// The class constraint comes next.
			//
			if (tparam.HasTypeConstraint) {
				CheckConversion (mc, context, atype, tparam, tparam.BaseType, loc);
			}

			//
			// Now, check the interfaces and type parameters constraints
			//
			if (tparam.Interfaces != null) {
				if (TypeManager.IsNullableType (atype)) {
					mc.Compiler.Report.Error (313, loc,
						"The type `{0}' cannot be used as type parameter `{1}' in the generic type or method `{2}'. The nullable type `{0}' never satisfies interface constraint",

				} else {
					foreach (TypeSpec iface in tparam.Interfaces) {
						CheckConversion (mc, context, atype, tparam, iface, loc);

			//
			// Finally, check the constructor constraint.
