Partial Classes
[edit | edit source]As the name indicates, partial class definitions can be split up across multiple physical files. To the compiler, this does not make a difference, as all the fragments of the partial class are grouped and the compiler treats it as a single class. One common usage of partial classes is the separation of automatically-generated code from programmer-written code.
Below is an example of a partial class.
Listing 1: Entire class definition in one file (file1.cs
)
public class Node
{
public bool Delete()
{
}
public bool Create()
{
}
}
Listing 2: Class split across multiple files
(file1.cs
)
public partial class Node
{
public bool Delete()
{
}
}
(file2.cs
)
public partial class Node
{
public bool Create()
{
}
}
