C# Visual studio designer视图无法获取正确的表单

我有一个C#的GUI项目。主窗口类的定义如下所示：

FormView.cs文件

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace RssReader
{
    partial class FormView : Form, IView
    {
        private SplitContainer MainContainer;
        private TreeView Items;
        private MenuStrip MainMenu;
        private ToolStripMenuItem File;
        private ToolStripMenuItem AddFeed;
        private ToolStripSeparator Separator;
        private ToolStripMenuItem Quit;
        private WebBrowser Message;

        /* some methods here which are implementing some kind of logic */
    } 
}

FormViewInit.cs文件

namespace RssReader
{
    partial class FormView
    {
        private void InitializeComponent()
        {
            this.MainContainer = new System.Windows.Forms.SplitContainer();
            this.Items = new System.Windows.Forms.TreeView();
            this.Message = new System.Windows.Forms.WebBrowser();
            this.MainMenu = new System.Windows.Forms.MenuStrip();
            this.File = new System.Windows.Forms.ToolStripMenuItem();
            this.AddFeed = new System.Windows.Forms.ToolStripMenuItem();
            this.Separator = new System.Windows.Forms.ToolStripSeparator();
            this.Quit = new System.Windows.Forms.ToolStripMenuItem();

            // the only component in this file is InitializeComponent method
            // all, what it does is just defining items on the form
            // and initializing it, i.e., creating instances, assign names etc.
        }
    }
}

FormViewEventHandlers.cs文件

using System;
using System.IO;
using System.Windows.Forms;

namespace RssReader
{
    partial class FormView
    {

        private void Quit_Click(object sender, EventArgs e)
        {
            if (MessageBox.Show("Do you really want to quit?", "Exit", MessageBoxButtons.YesNo)
                == DialogResult.Yes)
                Application.Exit();
        }

        // here goes event handler functions
    }
}

问题是：当我在visual studio 2010的“设计”视图中查看FormView.cs时，为什么会得到一个大小错误且没有元素的表单？

您的FormView中是否有构造函数？如果是，是否调用了InitializeComponent（）方法？

表单需要是

公共类。
通过将元素定义移动到FormViewInit.cs文件（使用InitializeComponent方法的文件）中来解决

文件以前是如何查看的，这是个问题。文件现在的外观：

public partial class FormView
{
    private System.ComponentModel.IContainer components = null;

    private SplitContainer MainContainer;
    private TreeView Items;
    private MenuStrip MainMenu;
    private ToolStripMenuItem File;
    private ToolStripMenuItem AddFeed;
    private ToolStripSeparator Separator;
    private ToolStripMenuItem Quit;
    private ContextMenuStrip ContextMenu;
    private ToolStripMenuItem RemoveItem;
    private WebBrowser Message;

    protected void InitializeComponent()
    {
        this.components = new System.ComponentModel.Container();
        this.MainContainer = new System.Windows.Forms.SplitContainer();
        this.Items = new System.Windows.Forms.TreeView();
        this.Message = new System.Windows.Forms.WebBrowser();
        this.MainMenu = new System.Windows.Forms.MenuStrip();
        this.File = new System.Windows.Forms.ToolStripMenuItem();
        this.AddFeed = new System.Windows.Forms.ToolStripMenuItem();
        this.Separator = new System.Windows.Forms.ToolStripSeparator();
        this.Quit = new System.Windows.Forms.ToolStripMenuItem();
        this.ContextMenu = new System.Windows.Forms.ContextMenuStrip(this.components);
        this.RemoveItem = new System.Windows.Forms.ToolStripMenuItem();
        this.MainContainer.Panel1.SuspendLayout();
        this.MainContainer.Panel2.SuspendLayout();
        this.MainContainer.SuspendLayout();
        this.MainMenu.SuspendLayout();
        this.ContextMenu.SuspendLayout();
        this.SuspendLayout();

        /*  there goes properties initializing, like setting names, sizes etc  */
    }

    // Added just in case

    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }
}

您应该以设计器模式查看FormViewInit.cs文件，而不是FormView.cs
类FormView具有公共构造函数，我正在调用方法InitializeComponent（）。它是默认构造函数吗
public FormView（）{…}
？它看起来像public FormView（）{/*这里有一些逻辑*/this.InitializeComponent（）；}我在所有3个文件中都添加了public关键字，但这没有帮助。我强烈建议您从“普通”表单开始，然后将它一点一点地更改为您需要的表单，每次检查是否破坏了设计器。是的，在我看来，InitializeComponet类没有正确地为窗体及其子控件设置正确的值（听起来您甚至缺少将元素添加到窗体中的代码）。设计师可以为您做很多这方面的工作。代码，为窗体设置正确的值，它的子项设置正确。我可以运行应用程序，并且它可以按预期工作。我唯一不能在designer视图中查看我的应用程序的东西。
