WebPart引用UserControl

Webpart引用UserControl有两种方法：

1. 引用QuickPart

2. 自己开发出一个WebPart暴露一个引用地址属性。代码如下：

using System;
    using System.Runtime.InteropServices;
    using System.Web.UI;
    using System.Web.UI.WebControls.WebParts;
    
    
    
    namespace WebPartCollection
    {
         
        [Guid("1c7e7f5f-c4d6-4628-8785-3804bc0f5c85")]
    public class UserControlWebPart : System.Web.UI.WebControls.WebParts.WebPart
        {
         
    public UserControlWebPart()
            {
         
    
            }
    
    private string _ControlPath;
            [Personalizable]
            [WebBrowsable]
            [WebDisplayName("Control File Path")]
    public string ControlPath
            {
         
    get { return _ControlPath; }
    set { _ControlPath = value; }
            }
    protected override void CreateChildControls()
            {
         
    
    base.CreateChildControls();
    
            }
    protected override void OnInit(EventArgs e)
            {
         
    base.OnInit(e);
    if (string.IsNullOrEmpty(_ControlPath))
    return ;
    try
                {
         
                    Control calendar = Page.LoadControl(_ControlPath);
    if (calendar!=null)
                    {
         
    this.Controls.Add(calendar);
                    }
                }
    catch (Exception ex)
                {
         
    this.Controls.Add(new LiteralControl(ex.Message));
                }
            }
        }
    }

ControlPath的地址格式如下：~/\_CONTROLTEMPLATES/Calendar.ascx，从以上的地址格式可以看出Calendar.ascx文件是放在12\\TEMPLATE\\CONTROLTEMPLATES文件夹里面。
