爲什麼我在C＃中調試時會得到空白表單？

Question

我剛剛擺脫了我所有的編譯器錯誤。其中一個問題是我不小心重命名了視覺形式本身，而不是我GUI上的單個文本框之一。當我去改變我在代碼中混淆的東西時，它似乎再次起作用。但是，每當我點擊F5進行調試時，我都會得到一個更小的空白窗口作爲我的GUI，而不是我在Visual Studio中設計的窗口。有什麼建議麼？

這裏是我的主（表格）類代碼：

using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 


namespace beehive1 
{ 
public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 

     Worker[] workers = new Worker[4]; 

     workers[0] = new Worker(new string[] { "Nectar collector", "Honey Manufacturing" }); 
     workers[1] = new Worker(new string[] { "Egg Care", "Baby Bee Tutoring" }); 
     workers[2] = new Worker(new string[] { "Hive Maintenance", "Sting Patrol" }); 
     workers[3] = new Worker(new string[] { "Nectar Collector", "Honey Manufacturing", 
      "Egg Care", "Baby Bee Manufacturing", "Hive Maintenance", "Sting Patrol" }); 


     queen = new Queen(workers); 
    } 

    Queen queen; 

    private void assignJob_Click(object sender, EventArgs e) 
    { 
     if (queen.AssignWork(workerBeeJob.Text, (int)shifts.Value) == false) 
      MessageBox.Show("No Workers Are Available To Do The Job " + workerBeeJob.Text + "", "The Queen Bee Says..."); 
     else 
      MessageBox.Show("The job " + workerBeeJob.Text + " will be done in " + shifts.Value + " shifts", "The Queen Bee Says..."); 

    } 

    private void button2_Click(object sender, EventArgs e) 
    { 
     report.Text = queen.WorkTheNextShift(); 
    } 
} 
}

也許應用程序不再連接到Form類？我試過了一個Clean Build和一個ReBuild，但它似乎沒有工作。

Answer 1

檢查您是否在Main方法中構造了一個Form（new Form()）實例而不是Form1()。

Answer 2

空格表示InitializeComponent()未被激活或this.Controls.Add未正確添加控件。嘗試逐步調試並激活所有CLR異常，以確保在構造函數中沒有發生異常。向我們展示形式的構造。

編輯：

這應該是檢查不檢查由上述可見的。 現在在調試模式下運行你的表單，看看是否有任何例外發生。 請加你怎麼稱呼你的形意：

Form1 newForm=new Form1(); 

Answer 3

有時視覺工作室獲得越野車（例如重命名你的項目/表格/目錄時）。直到我發現：

this.Controls.Add(*form object name*); 

在Form1.Designer.cs文件中缺少的行。這些是「自動生成」的線路，但顯然汽車生成並不總是順利。

我寫了一個快速又髒的python腳本，試圖解決這個問題。將腳本與xxx.Designer.cs文件的副本一起放入新目錄中並運行它。它會生成一個或許修復了xxx.Designer.cs.fix文件。節省了大量的手動複製粘貼。

import os 

#get current dir from which the script runs (should also contain the xxx.Designer.cs file) 
daDir = os.path.dirname(os.path.abspath(__file__)) 

#the file extension we're looking for 
ext = ".Designer.cs" 

#list of all files in the dir from which the script runs 
FileList = os.listdir(daDir) 

FileToOpen = "" 
ObjNameStr = "" 
OriginalFileName = "SORRY, AUTO FIXING FAILED" 

#the file to open (any first match for .Designer.cs) 
for str in FileList: 
    if (str.endswith(ext)): 
     OriginalFileName = str 
     FileToOpen = daDir + "\\" + str 
     break 

if FileToOpen != "": 
    print("File found: " + FileToOpen) 
    fileToFix = open(FileToOpen, 'r') 

    FormObjStrList = [] 

    for str in fileToFix: 
     # remove whitepaces/leading tabs 
     str = str.lstrip() 
     # get first part of string: "this.formobjectName" 
     str = str.partition(' ')[0] 
     if str.startswith("this.") and (str.count('.') == 1): 
      ObjNameStr = str 
      #add Form object to list if unique: 
      if (ObjNameStr not in FormObjStrList) and ("this.components" not in ObjNameStr): 
       #No more objects after SuspendLayout property 
       if ("this.SuspendLayout" in ObjNameStr): 
        break 
       else: 
        FormObjStrList.append("this.Controls.Add(" + ObjNameStr + ");") 

    # copy original file to a stringlist that will be the fixed file 
    FixedFile = fileToFix.read().splitlines() 

    # look op the location to copy the new string list into 
    i = 0 
    for str in FixedFile: 
     if ("this.AutoScaleMode" in str): 
      break 
     i += 1 

    i += 1 
    # Create the new xxx.Designer.cs fixed file by adding the extra generated lines 
    for str in FormObjStrList: 
     FixedFile.insert(i, str) 

else: 
    print("No fixable file found. ") 

print(FormObjStrList) 

# Save the new fixed file (manually check/correct this) 
FixedFileSave = open(OriginalFileName + ".fix", 'w') 
FixedFileSave.write("\n".join(FixedFile)) 
FixedFileSave.close() 

print("New fixed file saved as: " + OriginalFileName + ".fix") 
print("Please manually check if the generated file is correct for your project.")
