I\'ve gotten to a point where my main code file is about a thousand lines long and it\'s getting un-manageable; that is, I\'m starting to get confused and not know where to
Yes, but you need to be in the same namespace and declare the class just like you did in the main file, an example:
file1.cs
namespace Names
{
public partial class Hello
{
public void DoSomething() { }
}
}
file2.cs
namespace Names
{
public partial class Hello
{
public void Go() { DoSomething(); }
}
}
