Pourquoi j'obtiens un formulaire vierge lorsque je débogue en C#?

Question

Je viens de me débarrasser de toutes mes erreurs de compilation. Un des problèmes était que j'ai accidentellement renommé le formulaire visuel lui-même au lieu d'une des zones de texte individuelles sur mon interface graphique. Quand je suis allé changer ce que j'avais foiré dans le code, il semblait fonctionner à nouveau. Cependant, chaque fois que j'appuie sur F5 pour déboguer, j'obtiens une fenêtre plus petite et vide comme interface graphique, et non celle que j'ai conçue dans Visual Studio. Aucune suggestion?

Voici mon principal (Forms) Code de classe:

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 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(); 
    } 
} 
}

Peut-être que l'application n'est plus connecté à cette classe de formulaire? J'ai essayé une construction propre et un ReBuild, mais cela n'a pas semblé fonctionner.

Answer 1

Vérifiez si vous construisez une instance Form (new Form()) au lieu de Form1() dans votre méthode Main.

Answer 2

La forme vide signifie que InitializeComponent() n'est pas activé ou this.Controls.Add n'ajoute pas correctement les contrôles. essayez de déboguer étape par étape et activez toutes les exceptions CLR pour vous assurer qu'aucune exception ne se produit dans le constructeur. montrez-nous la construction de la forme aussi.

Edit:

cela doit être vérifié non vérifié comme vu ci-dessus. maintenant exécutez votre formulaire en mode débogage et voir si des excecptions se produisent. s'il vous plaît ajouter comment vous appelez votre formulaire sens:

Form1 newForm=new Form1(); 

Answer 3

studio Parfois visuel obtient poussette (par exemple lors du renommage votre projet/form /). Je luttais avec moi-même jusqu'à ce que j'ai découvert que:

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

lignes manquantes dans le fichier Form1.Designer.cs. Ce sont des lignes "générées automatiquement", mais apparemment la génération automatique ne va pas toujours bien.

J'ai écrit un petit script python rapide et sale qui essaie de résoudre ce problème. Placez le script dans un nouveau répertoire avec une copie de votre fichier xxx.Designer.cs et exécutez-le. Il va générer un fichier peut-être fixe xxx.Designer.cs.fix. Enregistre beaucoup de collage de copie manuelle.

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.")
