How to set large string inside HttpContent when using HttpClient?

.net, asp.net-web-api, c#, httpclient, httpcontent

Solution

I figured it out with the help of my friend. What you would want to do is avoid using FormUrlEncodedContent(), because it has restrictions on the size of the uri. Instead, you can do the following :

    var jsonString = JsonConvert.SerializeObject(post_parameters);
    var content = new StringContent(jsonString, Encoding.UTF8, "application/json");

Here, we don't need to use HttpContent to post to the server, StringContent gets the job done !

Problem

So, I created a `HttpClient` and am posting data using `HttpClient.PostAsync()`. I set the `HttpContent` using `HttpContent content = new FormUrlEncodedContent(post_parameters)`; where `post_parameters` is a list of Key value pairs `List<KeyValuePair<string, string>>` Problem is, when the `HttpContent` has a large value (an image converted to base64 to be transmitted) I get a URL is too long error. That makes sense - cause the url cant go beyond 32,000 characters. But how do I add the data into the `HttpContent` if not this way? Please help.
