Access class fields from partial class

Question

I'm currently in a scenario in which I have to make use of partial classes. In this partial class I have a few methods that need to address fields in the other class.

for example

Edit: I'm sorry: the first class is already declared partial!

public partial class myClass
{        
    private string _myString;

    public string myString
    {
        get { return _myString; }
        set { _myString = value; }
    }
}

and

public partial class myClass
{
    public void doSomething()
    {
        myString = "newString";
    }
}

The compiler says myString doesn't exist in the partial class!

How can I overcome this problem?

Answer 1

There are a few things you need to fix with the code you posted:

When using partial classes in C# all parts of the class must be declared as partial classes

You have:

 public class myClass {}
 public partial class myClass {}

Which needs to become:

public partial class myClass {}
public partial class myClass {}

Secondly, you're trying to set:

myString="newString";

but myString is a public property without a setter.

So either you add a setter when declaring myString:

public string myString
{
    get{ return _myString; }
    set { _myString = value; }
}

or just use:

_myString="newString";

in your second partial class file.
