Func delegate with ref variable
Solution 1:
It cannot be done by Func but you can define a custom delegate for it:
public delegate object MethodNameDelegate(ref float y);
Usage example:
public object MethodWithRefFloat(ref float y)
{
return null;
}
public void MethodCallThroughDelegate()
{
MethodNameDelegate myDelegate = MethodWithRefFloat;
float y = 0;
myDelegate(ref y);
}
Solution 2:
In .NET 4+ you can also support ref types this way...
public delegate bool MyFuncExtension<in string, MyRefType, out Boolean>(string input, ref MyRefType refType);
