获取项目中的所有表单到用户控件的属性组合框 [英] Get All Forms In a Project To User Control's Property Combo Box

问题描述

我有一个用户控件，我想创建一个dll并在其他项目中使用它。



我在该用户控件中有属性，应该在propertygrid中显示一个组合框，包含引用项目中的所有表单。我必须选择其中一个表单来设置物业价值。



我创建了以下自定义UITypeEditor

Hi,

I have a user control which I want to create a dll and use it in other project.

I have Property in that user control which should show a combo box in propertygrid contains all forms in the referenced project.I have to select one of that form to set the property value.

I Created the following custom UITypeEditor

internal class EntryFormEditor : ObjectSelectorEditor
      {
          protected override void FillTreeWithData(Selector theSel,
            ITypeDescriptorContext theCtx, IServiceProvider theProvider)
          {
              base.FillTreeWithData(theSel, theCtx, theProvider);  //clear the selection
              GrbDataGridView aCtl = (GrbDataGridView)theCtx.Instance;

              Type formType = typeof(Form);
              try
              {
                  //foreach (Assembly currentassembly in AppDomain.CurrentDomain.GetAssemblies())
                  //{
                  foreach (Type type in Assembly.GetExecutingAssembly().GetTypes())
                      {
                          if (formType.IsAssignableFrom(type))
                          {
                              try
                              {
                                  SelectorNode aNd = new SelectorNode(type.Name, type);

                                  theSel.Nodes.Add(aNd);
                              }
                              catch (Exception ex)
                              {
                              }
                              //if (type ==(Form) aCtl.EntryFormName)
                              //    theSel.SelectedNode = aNd;
                          }
                      //}
                  }
              }
              catch (Exception ex)
              {
              }
          }
      }

但是只显示dll中的表单而不是引用的项目





我做错了什么任何人都可以帮忙吗？

but showing only the forms inside the dll and not in the referenced project


What did I done wrong . Can anyone please Help ?

推荐答案

尝试 Assembly.GetEntryAssembly 而不是 Assembly.GetExecutingAssembly

在这一行

In this line

foreach (Type type in Assembly.GetExecutingAssembly().GetTypes())

你指的是正在执行的程序集（你的dll）。将其更改为您要检查的实际装配。





看看 GetCallingAssembly [ ^ ]。

看起来你可以在dll的入口点使用它获得立即调用方法的程序集。该链接指出了一些怪癖。



而且，由于我不知道你的应用程序的控制流，它也可以返回属于.NET框架的一些程序集。

[/编辑]

you're referring to the executing assembly (your dll). Change it to the actual assembly that you want to inspect.


Have a look at GetCallingAssembly[^].
Looks like you could use it in your dll's entry point to get the assembly of the immediate calling method. The link states some quirks, though.

And, since I have no idea of your application's control flow, it could as well return some assembly belonging to the .NET framework.
