我编写代码以在Form中添加UserControl:
UserControl edt = new UserControl();
edt.Name = "ItemEdit";
frm_Editor frm = new frm_Editor();
frm.Controls.Add(edt);
frm.Show();
然后,我在Form中找到UserControl:
Control[] tbxs = this.Controls.Find("ItemEdit", true);
if (tbxs != null && tbxs.Length > 0)
{
MessageBox.Show("Found");
}
但结果是null&& tbxs.Length = 0 请指导我处理问题的解决方案。非常感谢!

using System;
using System.Windows.Forms;
namespace FormTest
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Form1 frm = new Form1();
UserControl edt = new UserControl();
edt.Name = "ItemEdit";
frm.Controls.Add(edt);
Application.Run(frm);
}
}
}
using System.Windows.Forms;
namespace FormTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, System.EventArgs e)
{
Control[] tbxs = this.Controls.Find("ItemEdit", true);
if (tbxs != null && tbxs.Length > 0)
{
MessageBox.Show("Found");
}
}
}
