如何从其他课程调用输入对话框(Gorkem Gencay)
我如何使用'Gorkem Gencay'InputDialog从另一个类中调用它? 编辑:插入所有的代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace InputDialog
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public 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.StartPosition = FormStartPosition.CenterParent;
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;
}
private void Form1_Load(object sender, EventArgs e)
{
string input = "hede";
ShowInputDialog(ref input);
}
}
}
我正在尝试使用私人无效Form1_Load(对象发件人,EventArgs e) ,但不工作的以下方法:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace InputDialog
{
class Class1
{
Form1 frm = new Form1();
string input = "hede";
frm.ShowInputDialog(ref input);
}
}
该ShowInputDialog
方法被定义为静态的,因此您在调用它时需要使用类名称而不是对象名称。 假设ShowInputDialog
在Form1
类中定义,您应该按如下方式调用它:
string input = "hede";
Form1.ShowInputDialog(ref input);
顺便说一下,该方法被定义为private
因此您必须将其public
或internal
public
。
Class1
定义也有错误。 您不能从程序上下文中调用过程代码( frm.ShowInputDialog(ref input);
)。 定义一个方法并将你的对话框调用代码放入这个方法中:
class Class1
{
public static void TestDialogCall()
{
string input = "hede";
Form1.ShowInputDialog(ref input);
}
}
