I don't have an admin account so I cant test this. But from checking the documentation on what a Users.aliases looks like I think its probably going to be something like this.

 string userKey = "test@test.com";
 var body = new Google.Apis.Admin.Directory.directory_v1.Data.Alias { PrimaryEmail = userKey, AliasValue = "aliasemailid@test.com" };
 service.Users.Aliases.Insert(body, userKey).Execute();
