C#： 中文和UNICODE字符转换方法 及仿安居客地图实现。。。错误 GMap2未定义 解决办法 -VB 中文转为UNICODE字符

错误 GMap2未定义 解决办法 (关键在于：charset="utf-8" )

''/////************************* VB 中文转为UNICODE字符
''//中文转为UNICODE字符

代码

context.Response.ContentType = "application/json";
context.Response.Charset = "utf-8";
string txt = "{\"50697\":[\"\u65b0\u666f\u5bb6\u56ed\",392,39.8957115,116.4256382]}";
context.Response.Write(txt);

//Response.Write("\u65b0\u666f\u5bb6\u56ed" + "<br>");
//Response.Charset = "utf-8";

//string str = "动网新闻";
//string outStr = "";
//if (!string.IsNullOrEmpty(str))
//{
// for (int i = 0; i < str.Length; i++)
// {
// //将中文字符转为10进制整数，然后转为16进制unicode字符
// outStr += "\\u" + ((int)str[i]).ToString("x");
// }
//}
//Response.Write(outStr);
//Response.End();
