I'm attempting to call the geocodeAddresses method in the ArcGIS REST API in my C# application. The "addresses" input parameter is a potentially very long JSON string containing an array of a complex type. The code below works ok and I get a response from the API if the addresses param is a short JSON string containing only a few addresses, but if it is a very long string with many addresses I get an "Invalid URI: The Uri string is too long." exception when PostAsync() is called. So what I'm doing is just calling the API with a long url. How can I ensure the parameters are posted to the body of the request and not get an extremely long url?
