using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;

// Create a StringContent object with some data
var content = new StringContent("This is the request body.", Encoding.UTF8, "text/plain");

// Access the headers
HttpContentHeaders headers = content.Headers;

// Set common headers
headers.ContentType = new MediaTypeHeaderValue("application/json");
headers.ContentLength = 500; // Example: Set content length

// Add custom headers
headers.Add("X-Custom-Header", "MyValue");

// You can also get header values
string contentType = headers.ContentType.ToString();
string contentLength = headers.ContentLength.ToString();

Console.WriteLine($"Content-Type: {contentType}");
Console.WriteLine($"Content-Length: {contentLength}");
Console.WriteLine($"X-Custom-Header: {headers.GetValues("X-Custom-Header").FirstOrDefault()}");
