.net接收post请求并把数据转为字典格式

public sorteddictionary<string, string> getrequestpost()
{
int i = 0;
sorteddictionary<string, string> sarray = new sorteddictionary<string, string>();
namevaluecollection coll = request.form;

string[] requestitem = coll.allkeys;

for (i = 0; i < requestitem.length; i++)
{
sarray.add(requestitem[i], request.form[requestitem[i]]);
}

coll.clear();

return sarray;
}

调用：

sorteddictionary<string, string> spara = getrequestpost();
