Quelle est la version C# de InputDialog de VB.net?

Question

Quelle est la version C# de InputDialog de VB.net?

Answer 1

Ajouter une référence à Microsoft.VisualBasic, InputBox est dans l'espace de noms Microsoft.VisualBasic.Interaction:

string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", -1, -1); 

Answer 2

Il n'y a rien de tel: je recommande de l'écrire pour vous-même et de l'utiliser quand vous en avez besoin.

Answer 3

Vous voulez dire InputBox? Regardez dans l'espace de noms Microsoft.VisualBasic.

C# et VB.Net partagent une bibliothèque commune. Si une langue peut l'utiliser, l'autre peut le faire.

Answer 4

Il n'y en a pas. Si vous voulez vraiment utiliser le VB InputBox en C#, vous pouvez. Ajoutez juste la référence à Microsoft.VisualBasic.dll et vous le trouverez là.

Mais je suggère à pas l'utiliser. C'est moche et obsolète IMO.

Answer 5

Ajouter référence à Microsoft.VisualBasic et utiliser cette fonction:

string response = Microsoft.VisualBasic.Interaction.InputBox("What's 1+1?", "Title", "2", 0, 0); 

Le dernier numéro 2 est une position X/Y pour afficher la boîte de dialogue de saisie.

Answer 6

Pour résumer:

• Il est none in C#.

• Vous pouvez utiliser la boîte de dialogue à partir de Visual Basic en ajoutant une référence à Microsoft.VisualBasic:

  1. Dans l'Explorateur de solutions clic droit sur les Références dossier.
  2. Sélectionnez Ajouter Référence ...
  3. Dans l'onglet .NET (dans les nouveaux verions Visual Studio - onglet Assemblée) - sélectionnez Microsoft.VisualBasic
  4. Cliquez sur OK

Ensuite, vous pouvez utiliser le code mentionné précédemment:

string input = Microsoft.VisualBasic.Interaction.InputBox("Title", "Prompt", "Default", 0, 0); 

• Écrivez votre propre InputBox.
• Utiliser someone else's.

Cela dit, je suggère que vous considériez le besoin d'une boîte d'entrée en premier lieu. Les dialogues ne sont pas toujours la meilleure façon de faire les choses et parfois ils font plus de mal que de bien - mais cela dépend de la situation particulière.

Answer 7

Vous pouvez utiliser la boîte de dialogue Templet Exemple d'entrée suivante qui se trouve ici: link text

Answer 8

si vous ajoutez non seulement Microsoft.VisualBasic à votre liste de référence pour le projet, mais aussi vous devez déclarer « en utilisant Microsoft.VisualBasic; » il vous suffit donc d'utiliser 'Interaction.Inputbox ("...")' au lieu de Microsoft.VisualBasic.Interaction.Inputbox

Answer 9

Renvoie la chaîne entrée par l'utilisateur; chaîne vide s'ils ont frappé Annuler:

public static String InputBox(String caption, String prompt, String defaultText) 
    { 
     String localInputText = defaultText; 
     if (InputQuery(caption, prompt, ref localInputText)) 
     { 
      return localInputText; 
     } 
     else

Answer 10

Création dynamique d'une boîte de dialogue. Vous pouvez personnaliser à votre goût.

Remarque il n'y a pas de dépendance externe ici que WinForm

private static DialogResult ShowInputDialog(ref string input) 
    { 
     System.Drawing.Size size = new System.Drawing.Size(200, 70); 
     Form inputBox = new Form(); 

     inputBox.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog; 
     inputBox.ClientSize = size; 
     inputBox.Text = "Name"; 

     System.Windows.Forms.TextBox textBox = new TextBox(); 
     textBox.Size = new System.Drawing.Size(size.Width - 10, 23); 
     textBox.Location = new System.Drawing.Point(5, 5); 
     textBox.Text = input; 
     inputBox.Controls.Add(textBox); 

     Button okButton = new Button(); 
     okButton.DialogResult = System.Windows.Forms.DialogResult.OK; 
     okButton.Name = "okButton"; 
     okButton.Size = new System.Drawing.Size(75, 23); 
     okButton.Text = "&OK"; 
     okButton.Location = new System.Drawing.Point(size.Width - 80 - 80, 39); 
     inputBox.Controls.Add(okButton); 

     Button cancelButton = new Button(); 
     cancelButton.DialogResult = System.Windows.Forms.DialogResult.Cancel; 
     cancelButton.Name = "cancelButton"; 
     cancelButton.Size = new System.Drawing.Size(75, 23); 
     cancelButton.Text = "&Cancel"; 
     cancelButton.Location = new System.Drawing.Point(size.Width - 80, 39); 
     inputBox.Controls.Add(cancelButton); 

     inputBox.AcceptButton = okButton; 
     inputBox.CancelButton = cancelButton; 

     DialogResult result = inputBox.ShowDialog(); 
     input = textBox.Text; 
     return result; 
    } 

utilisation

string input="hede"; 
ShowInputDialog(ref input); 

Answer 11

Sans ajouter une référence à Microsoft.VisualBasic:

// "dynamic" requires reference to Microsoft.CSharp 
Type tScriptControl = Type.GetTypeFromProgID("ScriptControl"); 
dynamic oSC = Activator.CreateInstance(tScriptControl); 

oSC.Language = "VBScript"; 
string sFunc = @"Function InBox(prompt, title, default) 
InBox = InputBox(prompt, title, default)  
End Function 
"; 
oSC.AddCode(sFunc); 
dynamic Ret = oSC.Run("InBox", "メッセージ", "タイトル", "初期値");

Console.WriteLine(ret);

j'ai pu y parvenir en codant mon propre. Je n'aime pas m'étendre dans de grandes bibliothèques et m'en servir pour quelque chose de rudimentaire.

Forme et Designer:
