VB.netのInputBoxのC#バージョンとは何ですか?
Microsoft.VisualBasic
への参照を追加します。InputBox
はMicrosoft.VisualBasic.Interaction
名前空間にあります。
using Microsoft.VisualBasic;
string input = Interaction.InputBox("Prompt", "Title", "Default", -1, -1);
まとめると:
Microsoft.VisualBasicへの参照を追加することにより、Visual Basicからダイアログを使用できます。
次に、前述のコードを使用できます。
string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);
とはいえ、そもそも入力ボックスの必要性を考慮することをお勧めします。対話は常に物事を行うための最良の方法であるとは限らず、時には善よりも害を及ぼすことがありますが、それは特定の状況に依存します。
ダイアログボックスの動的作成。好みに合わせてカスタマイズできます。
winformを除き、ここには外部依存関係がないことに注意してください
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;
}
使用法
string input="hede";
ShowInputDialog(ref input);
ありません。 C#でVB InputBoxを本当に使用したい場合は可能です。 Microsoft.VisualBasic.dllへの参照を追加するだけで、そこに表示されます。
しかし、私はnotを使用することをお勧めします。くて時代遅れのIMOです。
プロジェクトの参照リストにMicrosoft.VisualBasicを追加するだけでなく、「using Microsoft.VisualBasic;」を宣言する必要もあります。したがって、Microsoft.VisualBasic.Interaction.Inputboxの代わりに 'Interaction.Inputbox( "...")'を使用するだけです。
ユーザーが入力した文字列を返します。ヒットした場合は空の文字列 Cancel:
public static String InputBox(String caption, String Prompt, String defaultText)
{
String localInputText = defaultText;
if (InputQuery(caption, Prompt, ref localInputText))
{
return localInputText;
}
else
{
return "";
}
}
String
をrefパラメーターとして返し、ヒットした場合はtrue
を返します OK、またはfalse
ヒットした場合 Cancel:

Microsoft.VisualBasic
への参照を追加し、この関数を使用します。
string response = Microsoft.VisualBasic.Interaction.InputBox("What's 1+1?", "Title", "2", 0, 0);
最後の2つの数字は、入力ダイアログを表示するX/Y位置です。
InputBoxのことですか? Microsoft.VisualBasic名前空間を見てください。
C#とVB.Netは共通のライブラリを共有しています。 1つの言語で使用できる場合、他の言語でも使用できます。
Microsoft.VisualBasicへの参照を追加せずに:
// "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");
詳細については、これらを参照してください。
ScriptControl
JScriptのMsgBox
JScriptの入力およびMsgBox
.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);
自分でコーディングすることでこれを達成できました。私は、大規模なライブラリにまで拡張して依存することは、初歩的なことを好まない。

これは、表示するテキストの量に応じてかなりのサイズを維持するために、多少の自動サイズ設定を示しています。また、私はそれが添えものを欠いていることを知っていますが、この同じジレンマに直面している人たちにとっては確実な前進です。
