后臺

復(fù)制代碼代碼如下:

protected void Page_Load(object sender, EventArgs e) 
{ 
Hashtable ht = new Hashtable(); 
string name = Request.Params["name"].ToString(); 
string birth = Request.Params["birthday"].ToString(); 
if (!string.IsNullOrEmpty(name) && !string.IsNullOrEmpty(birth)) 
{ 
//Response.ContentType = "Application/json"; 
//Response.Write(CreareJson("this is ok!", 1, name, birth)); 
ht.Add("info", "成功了"); 
ht.Add("sta", "狀態(tài)"); 
ht.Add("name", name); 
ht.Add("birth", birth); 
Response.Write(CreateJsonParams(ht)); 
} 
Response.End(); 
} 
private string CreateJsonParams(Hashtable items) 
{ 
string returnStr = ""; 
foreach(DictionaryEntry item in items) 
{ 
returnStr += "\"" + item.Key.ToString() + "\":\"" + item.Value.ToString() + "\","; 
} 
return "{" + returnStr.Substring(0,returnStr.Length-1) + "}"; 
}
