public class MyClass

public List<MyStruct> MyVariable

if (MyPrivateVariable == null)
{
MyPrivateVariable = new List<MyStruct>();
MyPrivateVariable.Add(new MyStruct());
MyPrivateVariable.Add(new MyStruct());

}
}
public void MyLoop()
{
foreach (MyStruct ms in MyVariable)
{
// Doesn't compile, but it works if you execute it through the Immediate window, or in Quickwatch
ms.MyBool = false;
// Compiles, works
MyFunction(ms);
}
}
public void MyFunction(MyStruct ms)
{
ms.MyBool = false;
}
}
}
Any reasonable explainations for this?
The compiler returns:
Error: Cannot modify members of 'ms' because it is 'foreach iteration variable'
EDIT:
Extra question:
I just tried changing a string from MyFunction
, and it doesn't actually update ms
. BUT: If I go to quickwatch and assign the same value there, it does update ms
. Why does this happen if it shouldn't even be compiling in the first place, shouldn't quickwatch throw an exception?
EDIT2:
Ok, quick watch also works on a copy of ms
, so that's why I can edit it's value, it doesn't actually alter the contents of MyPrivateVariable
