WinForm Control Development Summary (v) provide a type converter for complex properties of a control

I have already introduced the role of TypeConverterAttribute metadata in the previous article, this article will show you the concrete implementation through the code. In this case, I'm going to add a complex attribute to the control that has no function for the control, purely for demonstration purposes, and somewhat far-fetched.

Now add a scope property to the control code that you created in the previous article:

[Browsable (True)]

Public scope scope

{

get

{return

_scope;

}

set

{

_scope = value;

}

}

The type of this property is the scope class, and the code is as follows:

public class Scope

{

private Int32 _min;

Private Int32 _max;


Public scope ()

{

} public

scope (Int32 min, Int32 max)

{

_min = min　　　　　　　　　　　 ;

_max = max;

[Browsable (true)] public

Int32 Min

{get

{
  
    return _min;

}

set

{

_min = value;

}

[Browsable (true)] public

Int32 Max

{

get　　　　　　　　　　　 {return

_max;

}

set

{

_max = value;

}

}
