自定义控件把脚本文件编译为内嵌资源实例

我们在开发自定义的Web控件中,往往需要使用到系列客户端脚本代码,当我们发布控件时,为了方便发布和使用,一般不直接发布脚本文件,而是将脚本文件编译为内嵌的资源，然后从资源中读取脚本并注册。当然在ASP.NET里这个步骤比较简单,关键的是保证脚本文件的编译属性为"内嵌资源".

public class ScriptControl : Control {

    /// <summary>
    /// Register Client Script Block
    /// </summary>
    /// <param name="control">custom web control</param>
    /// <param name="scriptfile">resource script file name</param>
    public void RegisterScript(string scriptfile){
        if (!this.Page.IsClientScriptBlockRegistered(scriptfile)) {
            StreamReader reader = Res.GetStream(this.GetType(),scriptfile);
            using(reader){
                string script
                    = "<script language="javascript" type="text/javascript">rn<!--rn"
                    + reader.ReadToEnd()
                    + "rn//-->rn</script>";
                this.Page.RegisterClientScriptBlock(scriptfile, script);
            }
        }
    }
}

public class Res {
    public static StreamReader GetStream(Type type,string name){
        //Assembly assembly = Assembly.GetAssembly(type);
        Assembly assembly = type.Assembly;
        Stream stream = assembly.GetManifestResourceStream(type,name);
        return new StreamReader(stream);
    }
}

[DefaultProperty("Text"),
ToolboxData("<{0}:ShowDialogListBox runat=server></{0}:ShowDialogListBox>")]
public class ShowDialogListBox : ScriptControl {
    ......
    protected override void OnInit(EventArgs e) {
        this.RegisterScript("EnDeListBox.js");
    }
    ......
}
