IO Exception when sending large size of bytes using HttpWebRequest

[HappyMaggie]

We got this IO exception when sending relatively bigger size of bytes to WebAPI.

The IO exception happened when sending larger size of bytes from httpwebrequest.

We are writing pure .net C# code to call a web API by using HttpWebRequest.

The code is very similar to this page:

How to post JSON to a server using C#?



code :

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";

using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"user\":\"test\"," +
"\"password\":\"bla\"}";

streamWriter.Write(json);
}

var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}


We just using Json.net lib to convert object to json string.

When I changed to use real large size of bytes, it throws exception as following:
