VB.net的InputBox的C#版本是什么?
答案 0 :(得分:209)
添加对Microsoft.VisualBasic
的引用,InputBox
位于Microsoft.VisualBasic.Interaction
命名空间中:
using Microsoft.VisualBasic;
string input = Interaction.InputBox("Prompt", "Title", "Default", -1, -1);
答案 1 :(得分:101)
总结一下:
您可以通过添加对Microsoft.VisualBasic的引用来使用Visual Basic中的对话框:
然后你可以使用前面提到的代码:
string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);
那就是说,我建议您首先考虑输入框的需要。对话并不总是最好的做事方式,有时候弊大于利 - 但这取决于具体情况。
答案 2 :(得分:91)
动态创建对话框。您可以根据自己的喜好进行定制。
请注意,除了winform
之外,这里没有外部依赖关系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
string input="hede";
ShowInputDialog(ref input);

没有一个。如果你真的想在C#中使用VB InputBox,你可以。只需添加对Microsoft.VisualBasic.dll的引用,您就可以在那里找到它。
但我建议不使用它。它是丑陋的,过时的IMO。
答案 4 :(得分:5)
您不仅应该将Microsoft.VisualBasic添加到项目的引用列表中,还应该声明“使用Microsoft.VisualBasic;”所以你只需要使用'Interaction.Inputbox(“...”)'而不是Microsoft.VisualBasic.Interaction.Inputbox

返回用户输入的字符串;如果他们点击取消:
,则为空字符串 public static String InputBox(String caption, String prompt, String defaultText)
{
String localInputText = defaultText;
if (InputQuery(caption, prompt, ref localInputText))
{
return localInputText;
}
else
{
return "";
}
}
返回String
作为参考参数,如果点击确定则返回true
,如果点击<{1}}则返回<{1}} KBD>取消:
false
注意:任何代码都会发布到公共域中。无需归属。

添加对Microsoft.VisualBasic
的引用并使用此功能:
string response = Microsoft.VisualBasic.Interaction.InputBox("What's 1+1?", "Title", "2", 0, 0);
最后2个数字是显示输入对话框的X / Y位置。

你的意思是InputBox?只需查看Microsoft.VisualBasic命名空间。
C#和VB.Net共享一个公共库。如果一种语言可以使用它,另一种语言也可以使用它。
答案 8 :(得分:2)
不添加对Microsoft.VisualBasic的引用:
// "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");
有关详细信息,请参阅以下内容:
ScriptControl
MsgBox in JScript
Input and MsgBox in 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);

我能够通过编码自己来实现这一目标。我不喜欢延伸并依赖大型图书馆来做一些简陋的事情。

没有这样的事情:我建议你自己写,并在需要的时候使用它。
