如何将参数传递给继承UITypeEditor的类 [英] how do I pass an argument to a class that inherits UITypeEditor

问题描述

我已经为属性创建了一个编辑器.但是，我想将一些参数传递给编辑器的构造函数，但是我不确定如何执行此操作.

I have created an editor for a property. I would however like to pass some arguments to the constructor of the editor, but I am unsure as to how to do this.

FOO _foo = new foo();
[Editor(typeof(MyEditor), typeof(UITypeEditor))]
public object foo 
 {
 get { return _foo; }
 set {_foo = value;}
 }

〜

class MyEditor: UITypeEditor
{
  public override object EditValue(System.ComponentModel.ITypeDescriptorContext context, System.IServiceProvider provider, object value)
  {
    //some other code
    return obj;
  }
}

推荐答案

当然，您可以在myEditor类中添加另一个(已参数化的)构造函数，如下所示:

of course you can add another (parametrized) constructor to your myEditor class, something like this:

public class MyEditor: UITypeEditor
{
  // new parametrized constructor
  public MyEditor(string parameterOne, int parameterTwo...)
  {
    // here your code
  }

  ...
  ...
}

问题在于，您还应该控制谁调用该构造函数，因为只有这样，您才能决定要使用哪个构造函数，并且可以为参数指定/分配值.

the problem is that you should also be in control of who calls that constructor because only then you can decide which constructor to use and you can specify/assign a value to the parameters.
