我目前正在进行API HTTP POST项目。 我应该得到
"[{\"ID\":\"311d1977-4772-435a-92aa-028791c53154\",\"ParentID\":\"187a064e-ffea-45a2-9264-9acecff911e1\",\"Type\":\"txt\",\"OwnerID\":\"5bd087f0-070d-48bd-98b4-10ffa4b3b792\",\"Name\":\"Davinshi.txt\",\"CreatedBy\":\"5bd087f0-070d-48bd-98b4-10ffa4b3b792\",\"CreatedDate\":\"2015-06-05T04:11:33.187\",\"Status\":0,\"Mark\":null},{\"ID\":\"25c80f4e-679c-4093-ade9-0b99da480153\",\"ParentID\":\"187a064e-ffea-45a2-9264-9acecff911e1\",\"Type\":\"jpg\",\"OwnerID\":\"5bd087f0-070d-48bd-98b4-10ffa4b3b792\",\"Name\":\"leonid afremov.jpg\",\"CreatedBy\":\"5bd087f0-070d-48bd-98b4-10ffa4b3b792\",\"CreatedDate\":\"2015-06-05T04:11:46.61\",\"Status\":0,\"Mark\":null}
然而，使用以下代码我得到一个奇怪的输出
using (var client = new WebClient())
{
var val = new NameValueCollection();
foreach (var item in values)
{
val.Add(item.Key, item.Value);
}
var response = client.UploadValues(url, val);
return Encoding.Default.GetString(response);
}
这是输出

我认为HTTP POST Response正在将字符串作为逐字字符串读取。 我知道如何解决它？
谢谢！

当我运行您的代码时，Encoding.Default.GetString(response)的输出正是您在问题顶部发布的字符串。
在Visual Studio调试窗口中出现过度反斜杠转义的字符串，因为VS在显示字符串时会转义特殊字符，但如果您尝试将此字符串保存到文件中或在代码中以任何其他方式使用它，则会看到只有双引号会被转义，比如你问题顶部的字符串。

我发现API会自动将对象转换为json格式。 当我尝试在发送API之前序列化对象时会出现问题.Hence，就像Denis Yarkovoy所说的那样。它是双序列化的。
