填充Property Grid Combobox [英] Populate Property Grid Combobox

问题描述

下午所有人，



我已经开始学习C＃而且我遇到了一个使用属性网格的项目问题。我有一个16x16 png图像的目录。我的最终目标是使用文件名和图像填充组合框。



我看过几篇文章，其中包含静态值和列表，但我需要读取目录以获取文件名和图像。如果有人能帮助我走上正确的轨道，那就太好了。下面是我到目前为止编写的类，它将创建一个填充属性网格的对象。

Afternoon Everyone,

I have started learning C# and I'm running into an issue with my project that uses a property grid. I have a directory with 16x16 png images. My end goal is to populate a combobox with the file name and image.

I have looked at several articles that a being populated off static values and list but i would need to read a directory to get the file names and images. IF someone could help get me on the right track that would be great. Below is the class i have written so far that will create an object to populate a property grid.

using System;
using System.Drawing;
using System.Drawing.Design;
using System.Windows.Forms;
using System.ComponentModel;
using System.Globalization;
using System.IO;

namespace PropertyGrid_Testing
{
    class PG_Program
    {
        public object Action(string DisplayName, string Type, int Index, string Icon, string File, string Arguments)
        {
            Action MyWorker = new Action();

            MyWorker.DisplayName = DisplayName;
            MyWorker.Type = Type;
            MyWorker.Index = Index;
            MyWorker.Icon = Icon;
            MyWorker.File = File;
            MyWorker.Arguments = Arguments;

            return MyWorker;
        }
    }

    internal class Action
    {

        [Description("This is the Display Name used in the Context Menu.")]
        [Category("Detials")]
        public string DisplayName { get; set; }

        [ReadOnly(true)]
        [Description("This is the Type of item listed in the context menu. There can be Group, Action, or SEP. This setting gets set duing the new item creation.")]
        [Category("Detials")]
        public string Type { get; set; }

        [Description("This is the index in wish you want the item to display.")]
        [Category("Detials")]
        public int Index { get; set; }

        [Description("This is icon used to reference the context menu item.")]
        [Category("Detials")]
        public string Icon { get; set; }

        [Description("This is item you wish to invoke. This can be anything, ex: exe, bat, png, xlsx...")]
        [Category("Action")]
        [BrowsableAttribute(true)]
        [EditorAttribute(typeof(SaveFileNameEditor), typeof(System.Drawing.Design.UITypeEditor))]
        public string File { get; set; }

        [Description("(Optional) This references the arguments you wish to pass to the file you choose to invoke.")]
        [Category("Action")]
        public string Arguments { get; set; }
    }

    public class SaveFileNameEditor : UITypeEditor
    {
        public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
        {
            return UITypeEditorEditStyle.Modal;
        }

        public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
        {
            if (context == null || context.Instance == null || provider == null)
            {
                return base.EditValue(context, provider, value);
            }

            using (OpenFileDialog OFDialog = new OpenFileDialog())
            {
                if (value != null)
                {
                    OFDialog.InitialDirectory = System.IO.Path.GetDirectoryName(value.ToString());
                    OFDialog.FileName = value.ToString();
                }

                OFDialog.Title = "Select Action Item";
                OFDialog.Filter = "All files (*.*)|*.*";
                if (OFDialog.ShowDialog() == DialogResult.OK)
                {
                       value = OFDialog.FileName;
                }
            }

            return value;
        }
    }
}
