Dodaj odwołanie do Microsoft.VisualBasic
, InputBox
znajduje się w Microsoft.VisualBasic.Interaction
przestrzeni nazw:
using Microsoft.VisualBasic;
string input = Interaction.InputBox("Prompt", "Title", "Default", x_coordinate, y_coordinate);
Tylko pierwszy argument za prompt
jest obowiązkowy
InputBox
natywnie nie obsługuje zamaskowanych danych wejściowych. Będziesz musiał rzucić własny formularz wejściowy.
using Microsoft.VisualBasic
więc po prostu napiszInteraction.InputBox()
Podsumowując:
Możesz użyć okna dialogowego z Visual Basic, dodając odwołanie do Microsoft.VisualBasic:
Następnie możesz użyć wspomnianego wcześniej kodu:
string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);
To powiedziawszy, sugeruję, abyś najpierw rozważył potrzebę pola wprowadzania. Dialogi nie zawsze są najlepszym sposobem robienia rzeczy i czasami przynoszą więcej szkody niż pożytku - ale to zależy od konkretnej sytuacji.
Dynamiczne tworzenie okna dialogowego. Możesz dostosować do swojego gustu.
Zauważ, że nie ma tutaj żadnej zależności zewnętrznej poza winform

string input="hede";
ShowInputDialog(ref input);
Nie ma takiego. Jeśli naprawdę chcesz użyć VB InputBox w C #, możesz. Po prostu dodaj odniesienie do Microsoft.VisualBasic.dll, a znajdziesz je tam.
Ale radziłbym go nie używać. To brzydka i przestarzała IMO.
cancel
z empty input string
faktycznie jest błąd IMO.
Nie tylko należy dodać Microsoft.VisualBasic do listy referencyjnej projektu, ale także zadeklarować „using Microsoft.VisualBasic;” więc wystarczy użyć „Interaction.Inputbox („ ... ”)” zamiast Microsoft.VisualBasic.Interaction.Inputbox
Zwraca ciąg znaków wprowadzony przez użytkownika; pusty ciąg, jeśli trafią Cancel:

Zwraca parametr String

Masz na myśli InputBox? Wystarczy spojrzeć na przestrzeń nazw Microsoft.VisualBasic.
C # i VB.Net mają wspólną bibliotekę. Jeśli jeden język może się nim posługiwać, inny też może.
Bez dodawania odwołania do 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");
Zobacz te, aby uzyskać więcej informacji:
ScriptControl
MsgBox w JScript
Input i MsgBox w JScript
.NET 2.0:
string sFunc = @"Function InBox(prompt, title, default)
InBox = InputBox(prompt, title, default)
End Function
";
Type tScriptControl = Type.GetTypeFromProgID("ScriptControl");
object oSC = Activator.CreateInstance(tScriptControl);
// https://github.com/mono/mono/blob/master/mcs/class/corlib/System/MonoType.cs
// System.Reflection.PropertyInfo pi = tScriptControl.GetProperty("Language", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.CreateInstance| System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.SetProperty | System.Reflection.BindingFlags.IgnoreCase);
// pi.SetValue(oSC, "VBScript", null);
tScriptControl.InvokeMember("Language", System.Reflection.BindingFlags.SetProperty, null, oSC, new object[] { "VBScript" });
tScriptControl.InvokeMember("AddCode", System.Reflection.BindingFlags.InvokeMethod, null, oSC, new object[] { sFunc });
object ret = tScriptControl.InvokeMember("Run", System.Reflection.BindingFlags.InvokeMethod, null, oSC, new object[] { "InBox", "メッセージ", "タイトル", "初期値" });
Console.WriteLine(ret);
Udało mi się to osiągnąć, kodując własne. Nie lubię rozszerzać się i polegać na dużej bibliotece jako czegoś podstawowego.

Zauważ, że pokazuje to trochę automatycznego rozmiaru, aby zachować ładność w zależności od tego, ile tekstu, o który prosisz, wyświetla. Wiem też, że brakuje mu dzwonków i gwizdków, ale jest to solidny krok naprzód dla tych, którzy stoją przed tym samym dylematem.
