c＃winform在运行时检查对象

Question

我想在运行时在GUI中显示任意对象的公共属性/值。

是否有一个winform允许用户查看调试模式下的任何对象的内容？该对象将包含许多字典>，并且能够在运行时扩展和查看这些列表的内容将会很好。

如果不可用，有没有办法实现类似的功能？

感谢

Answer 1

有PropertyGrid：

var form = new Form(); 

form.Controls.Add 
(
    new PropertyGrid() 
    { 
    SelectedObject = new { A = "Hi", B = new [] { 32, 40 } } 
    } 
); 

form.Show(); 

这是从如何调试一个作品很远，但它可以很容易地修改，以处理您的任何特殊情况。

所有你需要做的就是创建一个带有PropertyGrid的窗体。然后设置选定的对象。

using xxx.CFM.UI.Core; 
using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace xxx.CFM.UI.Forms 
{ 
    /// <summary> 
    /// Form used to inspect objects at runtime 
    /// </summary> 
    public partial class frmInspector : BaseForm 
    { 
     #region Properties 

     /// <summary> 
     /// Gets or Sets the 
     /// </summary> 
     public object SelectedObject 
     { 
      get { return propertyGrid.SelectedObject; } 
      set { propertyGrid.SelectedObject = value; } 
     } 

     #endregion Properties 

     #region Constructor 

     /// <summary> 
     /// Constructor 
     /// </summary> 
     public frmInspector(object objectToInspect) 
     { 
      try 
      { 
       InitializeComponent(); 

       this.SelectedObject = objectToInspect; 
      } 
      catch (Exception ex) 
      { 
       UIMessage.DisplayError(ex); 
      } 
     } 

     #endregion Constructor 

     #region Events 

     /// <summary> 
     /// Closes the form 
     /// </summary> 
     /// <param name="sender">object</param> 
     /// <param name="e">args</param> 
     private void btnClose_Click(object sender, EventArgs e) 
     { 
      try 
      { 
       this.Close(); 
      } 
      catch (Exception ex) 
      { 
       UIMessage.DisplayError(ex); 
      } 
     } 

     #endregion Events 
    } 
} 

我在例如网格使用上下文菜单上的期望它下面的数据记录：

/// <summary> 
    /// Opens the object inspector 
    /// </summary> 
    /// <param name="sender">object</param> 
    /// <param name="e">args</param> 
    private void inspectorMenuItem_Click(object sender, EventArgs e) 
    { 
     try 
     { 
      //Get the payload 
      SectionDataTreeListMenuItemPayload payload = (sender as ToolStripMenuItem).Tag as SectionDataTreeListMenuItemPayload; 

      if (payload == null || payload.DataRow == null) 
       return; 

      using (frmInspector frmInspector = new frmInspector(payload.DataRow)) 
       frmInspector.ShowDialog(); 
     } 
     catch (Exception ex) 
     { 
      UIMessage.DisplayError(ex); 
     } 
    } 

另一个小窍门，你所能做的就是确保表单仅当通过使用“编译器指令”使用下面的代码在调试模式下构建时才可用。 （如果你希望它只用于调试当然）

#if DEBUG 

       //Add object inspector menu item if built in debug mode 
       ToolStripMenuItem inspectorMenuItem = new ToolStripMenuItem(); 
       inspectorMenuItem.Text = "Inspect Object"; 
       inspectorMenuItem.Image = Properties.Resources.Inspect24x24; 
       inspectorMenuItem.Click += inspectorMenuItem_Click; 
       inspectorMenuItem.Tag = payload; 
       contextMenuStrip.Items.Add(inspectorMenuItem); 

#endif
