This is easy and basic. I havnt written in C# for a long time. I have a project with 3 classes. The main class and 2 custom classes. I forgot how to use strings created in one and call it in another. below is the example. I have a list and I want to use it in another class. I think I have to put it in the method not sure though. Thanks. All the classes are part of the same name space.

这是一个非常简单的示例.

Here is a very simple example.

public class ParentClass
{
    public void Demo()
    {
        var c1 = new Class1();
        var c2 = new Class2(c1.NameList);
    }
}

public class Class1
{
    private List<string> mNames;
    public List<string> NameList { get { return mNames; } }
    public List<string> NameList2  { get; set; }
    public Class1()
    {
        mNames = new List<string>() { "Karen","Joe"};
        NameList2 = new List<string>() { "Bill", "Mary","Ann" };
    }
}
public class Class2
{
    private List<string> mNames;
    public Class2(List<string> pNameList)
    {
        mNames = pNameList;
    }
    public void Demo()
    {
        mNames.ForEach(name => Console.WriteLine(name));
