我调用Web API的提交操作时，出现异常，异常让人看不明白，是那个地方错了吗？求大神指点。
以下是调用时使用的代码：
private void button2_Click(object sender, EventArgs e)
{
ApiClient client = new ApiClient("win-0vs5fckt8od/K3Cloud/");
object[] loginInfo = new object[] {
"000c29be5fc2930011e46f3f1d2e719a",//帐套Id
"Daly",//用户名
"888888",//密码
2052};//语言id
var ret = client.Execute
var result = JObject.Parse(ret)["LoginResultType"].Value
if (result == 1)
{
JObject js = new JObject();
js.Add("CreateOrgId", "0");
JArray array = new JArray();
array.Add("ABC");
js.Add("Numbers", array );
ret = client.Execute
js.ToString () });
JObject j = JObject.Parse(ret);
MessageBox.Show(j["Message"].ToString());
}
}以下是返回结果：

不止提交操作，其他的如审核删除反审核之类的操作，都有同样的问题。
不知道代码的什么位置有错误，求指点。
