把你的

var res

放在

in

Sys.Serialization.JavaScriptSerializer.serialize();

之后尝试你的代码...

after that try your code...

.ajax （{
类型： POST，
contentType： application / json，
url： HuntableWebService.asmx / uploadfile，
data： {'res'：' + Sys.Serialization.JavaScriptSerializer.serialize（res）+ '}，
dataType： JSON，
异步： true ，
成功：功能（响应）{
< span class =code-comment> // var res = response.d;
alert（response.d）;
}
}）;

.ajax({ type: "POST", contentType: "application/json", url: "HuntableWebService.asmx/uploadfile", data: "{'res':'" + Sys.Serialization.JavaScriptSerializer.serialize(res) + "'}", dataType: "JSON", async: true, success: function (response) { //var res = response.d; alert(response.d); } });
