Can you explain the concept of partial classes in programming?

Partial classes in C# allow splitting the definition of a single class across multiple files. This is useful when the class is large or when code is generated automatically (for example, by a form designer), and you want to add your own logic without modifying the generated code.

All parts of a partial class are combined by the compiler into a single class. It is important that all parts have the same name and are in the same namespace.

Example:

// File1.cs
public partial class MyClass
{
    public void Method1() { }
}

// File2.cs
public partial class MyClass
{
    public void Method2() { }
}

As a result, MyClass will contain both methods Method1 and Method2.
