非静态方法或字段错误需要一个对象

Question

Type cstype = this.GetType();


        ClientScriptManager cs = Page.ClientScript;  ///Broken line


        if (!cs.IsStartupScriptRegistered(cstype, "loadvideo"))
        {
            StringBuilder cstext3 = new StringBuilder();
            cstext3.Append("jwplayer(\"vidplayer\").setup({");
            cstext3.Append("flashplayer:\"./players/player.swf\",");
            cstext3.Append("file: \"");
            cstext3.Append("./video.mp4");
            cstext3.Append("\",height: 270,");
            cstext3.Append("width: 400");
            cstext3.Append("});");
            cs.RegisterStartupScript(cstype, "loadvideo", cstext3.ToString(), true);

有

"An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.ClientScript.get'"

指定行出错。我该如何解决？

Answer 1

假设此代码来自页面本身，请试试这个...

ClientScriptManager cs = this.ClientScript;  ///Broken line

Answer 2

Page.ClientScript 不是静态的属性，所以你不能这样使用它。假设您有一个名为 pageInstance 的 Page 实例，可以在方法中访问它，请改用下面的方法：

ClientScriptManager cs = pageInstance.ClientScript;
