创建第一个Silverlight程序

之前学过WP开发, 技术相似的silverlight技术，虽然已经很少地方使用，但是xaml技术还是相通的。

Silverlight3 和4创建silverlight对象已经不用之前的createobject 方法。

 

取而代之，用<object>标签

 

//兼容不同浏览器
<script type="text/javascript" src="Silverlight.js"></script>
//异常处理
 <script type="text/javascript">
        function onSilverlightError(sender, args) {
            var appSource = "";
            if (sender != null && sender != 0) {
              appSource = sender.getHost().Source;
            }
            
            var errorType = args.ErrorType;
            var iErrorCode = args.ErrorCode;

            if (errorType == "ImageError" || errorType == "MediaError") {
              return;
            }

            var errMsg = "Silverlight 应用程序中未处理的错误 " +  appSource + "\n" ;

            errMsg += "代码: "+ iErrorCode + "    \n";
            errMsg += "类别: " + errorType + "       \n";
            errMsg += "消息: " + args.ErrorMessage + "     \n";

            if (errorType == "ParserError") {
                errMsg += "文件: " + args.xamlFile + "     \n";
                errMsg += "行: " + args.lineNumber + "     \n";
                errMsg += "位置: " + args.charPosition + "     \n";
            }
            else if (errorType == "RuntimeError") {           
                if (args.lineNumber != 0) {
                    errMsg += "行: " + args.lineNumber + "     \n";
                    errMsg += "位置: " +  args.charPosition + "     \n";
                }
                errMsg += "方法名称: " + args.methodName + "     \n";
            }

            引发新错误(errMsg);
        }
    </script>

 最重要的是必须开启asp.net服务器才能显示运行.(这个后面考究,想半天没明白)
