我看到了两种不同的方法来为共享点创建 Web 部件。哪一款最受大家青睐？

任何涉及 VSeWSS 的事情都会以痛苦告终，所以方法 1 肯定不适用。方法 2 也不理想，因为将 html 元素设置为控件变得难以管理，其程度超出了您在该演示中看到的程度。我使用一个相当简单的通用基类，它将用户控件作为类型参数，并让我将所有布局与共享点基础结构很好地分开。如果您以编程方式创建页面/Web 部件，则大多数 Web 部件 xml 也是可选的。

public abstract class UserControlWebPart<T> : Microsoft.SharePoint.WebPartPages.WebPart where T:UserControl
{
    protected UserControlWebPart()
    {
        this.ExportMode = WebPartExportMode.All;
    }

    protected virtual void TransferProperties(T ctrl)
    {
        var tc = typeof(T);
        var tt = this.GetType();

        foreach (var p in tt.GetProperties()) {
            if (p.IsDefined(typeof(ControlPropertyAttribute), true)) {
                foreach (var p2 in tc.GetProperties()) {
                    if (p2.Name == p.Name) {
                        p2.SetValue(ctrl, p.GetValue(this, null), null);
                    }
                }
            }
        }
   }


    protected override void CreateChildControls()
    {
        string controlURL = ControlFolder+typeof(T).Name+".ascx";
        var ctrl = Page.LoadControl(controlURL) as T;
        TransferProperties(ctrl);
        this.Controls.Add(ctrl);
    }

    protected virtual string ControlFolder
    {
        get {
            return "~/_layouts/UserControlWebParts/";
        }
    }

}

Anything involving VSeWSS is just going to end in pain, so method 1 is definitely out. Method 2 isn't ideal either, as setting up html elements as controls becomes unmanageable at a level just beyond what you see in that demo. I use a fairly simple generic base class that takes a user control as a type parameter and lets me keep all the layout nicely seperated from the sharepoint infrastructure. If you are creating pages/web parts programatically most of the web part xml turns out to be optional also.

public abstract class UserControlWebPart<T> : Microsoft.SharePoint.WebPartPages.WebPart where T:UserControl
{
    protected UserControlWebPart()
    {
        this.ExportMode = WebPartExportMode.All;
    }

    protected virtual void TransferProperties(T ctrl)
    {
        var tc = typeof(T);
        var tt = this.GetType();

        foreach (var p in tt.GetProperties()) {
            if (p.IsDefined(typeof(ControlPropertyAttribute), true)) {
                foreach (var p2 in tc.GetProperties()) {
                    if (p2.Name == p.Name) {
                        p2.SetValue(ctrl, p.GetValue(this, null), null);
                    }
                }
            }
        }
   }


    protected override void CreateChildControls()
    {
        string controlURL = ControlFolder+typeof(T).Name+".ascx";
        var ctrl = Page.LoadControl(controlURL) as T;
        TransferProperties(ctrl);
        this.Controls.Add(ctrl);
    }

    protected virtual string ControlFolder
    {
        get {
            return "~/_layouts/UserControlWebParts/";
        }
    }

}
