什么是VB.net的InputDialog的C#版本？

什么是VB.net的InputBox的C#版本？

加入一个参考Microsoft.VisualBasic,InputBox是在Microsoft.VisualBasic.Interaction命名空间:

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

---

呸...西方最快的枪哈哈....无论如何我在对象浏览器中查找了实际签名并且提示出现在标题之前,所以它首先是"提示"然后是"标题"..最后2个数字是X/Y坐标显示输入框

---

只需导入`using Microsoft.VisualBasic`,你就可以编写`Interaction.InputBox()`

---

@ hims056`InputBox`本身不支持屏蔽输入.您需要滚动自己的输入表单.

---

我已经搜索过至少10次了.总是得到这个答案.如果可以,我会再次投票.谢谢!

把它们加起来:

有没有在C# .

您可以通过添加对Microsoft.VisualBasic的引用来使用Visual Basic中的对话框:

在解决方案资源管理器中,右键单击" 引用"文件夹.

选择添加参考...

在.NET选项卡中(在较新的Visual Studio版本 - 程序集选项卡中) - 选择Microsoft.VisualBasic

单击" 确定"

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);

编写自己的InputBox.

使用别人的.

也就是说,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,有时它们弊大于利 - 但这取决于具体情况.

是的,他们是.但在我看来,在大多数情况下,他们的运输代码都不好.

动态创建对话框.您可以根据自己的口味定制.

注意除了winform之外没有外部依赖

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;
    }

用法

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

---

inputBox.StartPosition = FormStartPosition.CenterParent; 将对话框置于父窗口的中心.

---

好的,很简单,我找到了:inputBox.AcceptButton = okButton; inputBox.CancelButton = cancelButton;

+1用于编写自己的代码并在此处共享!其他人太懒了,只想轻松获得免费积分.

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.

但我建议不要使用它.它是丑陋的,过时的IMO.

---

我觉得你太善良了.它比那更难看和过时了!

---

无法从`空输入字符串'识别`取消`实际上是一个错误的IMO.

5> 小智..：

---

您不仅应该将Microsoft.VisualBasic添加到项目的引用列表中,还应该声明'using Microsoft.VisualBasic;' 所以你只需要使用'Interaction.Inputbox("...")'而不是Microsoft.VisualBasic.Interaction.Inputbox

---

如果你只使用它一次,如果OP决定他们不再需要InputBox,这会增加混乱.此外,这应该是一个评论.

返回用户输入的字符串; 如果它们击中空字符串Cancel:

    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ref参数,true如果它们命中OK,或者false如果它们命中,则返回Cancel:

    public static Boolean InputQuery(String caption, String prompt, ref String value)
    {
        Form form;
        form = new Form();
        form.AutoScaleMode = AutoScaleMode.Font;
        form.Font = SystemFonts.IconTitleFont;

        SizeF dialogUnits;
        dialogUnits = form.AutoScaleDimensions;

        form.FormBorderStyle = FormBorderStyle.FixedDialog;
        form.MinimizeBox = false;
        form.MaximizeBox = false;
        form.Text = caption;

        form.ClientSize = new Size(
                    Toolkit.MulDiv(180, dialogUnits.Width, 4),
                    Toolkit.MulDiv(63, dialogUnits.Height, 8));

        form.StartPosition = FormStartPosition.CenterScreen;

        System.Windows.Forms.Label lblPrompt;
        lblPrompt = new System.Windows.Forms.Label();
        lblPrompt.Parent = form;
        lblPrompt.AutoSize = true;
        lblPrompt.Left = Toolkit.MulDiv(8, dialogUnits.Width, 4);
        lblPrompt.Top = Toolkit.MulDiv(8, dialogUnits.Height, 8);
        lblPrompt.Text = prompt;

        System.Windows.Forms.TextBox edInput;
        edInput = new System.Windows.Forms.TextBox();
        edInput.Parent = form;
        edInput.Left = lblPrompt.Left;
        edInput.Top = Toolkit.MulDiv(19, dialogUnits.Height, 8);
        edInput.Width = Toolkit.MulDiv(164, dialogUnits.Width, 4);
        edInput.Text = value;
        edInput.SelectAll();


        int buttonTop = Toolkit.MulDiv(41, dialogUnits.Height, 8);
        //Command buttons should be 50x14 dlus
        Size buttonSize = Toolkit.ScaleSize(new Size(50, 14), dialogUnits.Width / 4, dialogUnits.Height / 8);

        System.Windows.Forms.Button bbOk = new System.Windows.Forms.Button();
        bbOk.Parent = form;
        bbOk.Text = "OK";
        bbOk.DialogResult = DialogResult.OK;
        form.AcceptButton = bbOk;
        bbOk.Location = new Point(Toolkit.MulDiv(38, dialogUnits.Width, 4), buttonTop);
        bbOk.Size = buttonSize;

        System.Windows.Forms.Button bbCancel = new System.Windows.Forms.Button();
        bbCancel.Parent = form;
        bbCancel.Text = "Cancel";
        bbCancel.DialogResult = DialogResult.Cancel;
        form.CancelButton = bbCancel;
        bbCancel.Location = new Point(Toolkit.MulDiv(92, dialogUnits.Width, 4), buttonTop);
        bbCancel.Size = buttonSize;

        if (form.ShowDialog() == DialogResult.OK)
        {
            value = edInput.Text;
            return true;
        }
        else
        {
            return false;
        }
    }

    /// 

    /// Multiplies two 32-bit values and then divides the 64-bit result by a 
    /// third 32-bit value. The final result is rounded to the nearest integer.
    /// 
    public static int MulDiv(int nNumber, int nNumerator, int nDenominator)
    {
        return (int)Math.Round((float)nNumber * nNumerator / nDenominator);
    }
