I am trying to create a Patch request with theHttpClient in dotnet core. I have found the other methods,

using (var client = new HttpClient())
{
    client.GetAsync("/posts");
    client.PostAsync("/posts", ...);
    client.PutAsync("/posts", ...);
    client.DeleteAsync("/posts");
}

but can't seem to find the Patch option. Is it possible to do a Patch request with the HttpClient? If so, can someone show me an example how to do it?


Thanks to Daniel A. White's comment, I got the following working.

using (var client = new HttpClient())
{       
    var request = new HttpRequestMessage(new HttpMethod("PATCH"), "your-api-endpoint");

    try
    {
        response = await client.SendAsync(request);
    }
    catch (HttpRequestException ex)
    {
        // Failed
    }
}

    var method = "PATCH";
    var httpVerb = new HttpMethod(method);
    var httpRequestMessage =
        new HttpRequestMessage(httpVerb, path)
        {
            Content = stringContent
        };
    try
    {
        var response = await client.SendAsync(httpRequestMessage);
        if (!response.IsSuccessStatusCode)
        {
            var responseCode = response.StatusCode;
            var responseJson = await response.Content.ReadAsStringAsync();
            throw new MyCustomException($"Unexpected http response {responseCode}: {responseJson}");
        }
