Whenever I want to send an object to web api server I use StringContent to add format to HTTP content, for example to add Customer object as json to server:

 public void AddCustomer(Customer customer)
    {
        String apiUrl = "Web api Address";
        HttpClient _client= new HttpClient();

        string JsonCustomer = JsonConvert.SerializeObject(customer);
        StringContent content = new StringContent(JsonCustomer, Encoding.UTF8, "application/json");
        var response = _client.PostAsync(apiUrl, content).Result;

    }

Every response that is basically text encoded can be represented as StringContent.

Html reponse is text too (with proper content type set):
```
response.Content = new StringContent("<html><head>...</head><body>....</body></html>")
```
On the other side, if you download/upload file, that is binary content, so it cannot be represented by string.

StringContent class creates a formatted text appropriate for the http server/client communication. After a client request, a server will respond with a HttpResponseMessageand that response will need a content, that can be created with the StringContent class.

Example:
```
 string csv = "content here";
 var response = new HttpResponseMessage();
 response.Content = new StringContent(csv, Encoding.UTF8, "text/csv");
 response.Content.Headers.Add("Content-Disposition", 
                              "attachment; 
                              filename=yourname.csv");
 return response;
```
In this example, the server will respond with the content present on the csv variable.

It provides HTTP content based on a string.

Example:

Adding the content on HTTPResponseMessage Object
```
response.Content = new StringContent("Place response text here");
```
