Replace parameters in URL parameter for HttpRequestMessage

Question

How to replace a parameter in C# HttpRequestMessage URL?

I have the following code,

using (var request = new HttpRequestMessage(new HttpMethod("POST"), "http://MyService/Ids/63847/create"))

I want to replace 63847 with something like {0}, and have it set up dynamically. Is there a way to do that in C#?

using (var request = new HttpRequestMessage(
    new HttpMethod("POST"), 
    string.Format("http://MyService/Ids/{0}/create", 12345)
))
