how to GET https content using client certificate

How to retrieve page over https using client and server certificate in .NET 6 C# ?

Using curl this works:

curl --no-progress-bar --silent --show-error -H "OrgId: 123456" --insecure --key private.key --cert server.crt https://example.com --output result.xml

How to convert this to C# ?

private.key file is text file in format

-----BEGIN RSA PRIVATE KEY-----
MIIEpAIBAAKCAQEAxTvKy3WRPqli9ODpIcTb8Bhnxa2x+8xip/kWq...

server.crt is text file in format

-----BEGIN CERTIFICATE-----
MIIEnzCCAoegAwIBAgIIIJKu2MhhxF0wDQYJKoZIhvcNAQENBQAwLjEeMBwGA1UE

This is ASP.NET 6 MVC application running in Debian and Windows servers.

@Andrus , Welcome to Microsoft Q&A, I am not familar with curl command, but based on my search, you could try the following tool to convert curl to c#.

I tried curl to c# online version https://curl.olsh.me/ to convert

curl --key private.key --cert server.crt https://example.com

It throws errors

Certificate type "Pem" is not supported
Parameter "--key" is not supported

and generates code

var handler = new HttpClientHandler();
using (var httpClient = new HttpClient(handler))
    using (var request = new HttpRequestMessage(new HttpMethod("GET"), "https://example.com/"))
        request.Headers.TryAddWithoutValidation("OrgId", "123456"); 
        var response = await httpClient.SendAsync(request);

Server requires private key from file private.key for authentication.
How to pass private key to server ?
