In fact, your method declaration will look something like this: It doesn't mean, though, that you can use void when defining your service. This type exists primarily for documentation purposes, however: Using the Empty type says in a relatively unambiguous way that your method doesn't return a value (though unhandled errors should still, of course, be propagated back to the client). Rpc DeleteCustomer (CustomerIdRequest) returns () proto file to flag that a service doesn't return anything looks like this: There's no equivalent to the void keyword in ProtoBuf but the Empty type lets you define a service that doesn't return a value. proto file, your method doesn't have to accept any parameters…but it must have some return type. The Empty type has a different purpose: Rather than using it in a message, I use it to define methods in my service. To convert a Timestamp back into a date, I'd use the Timestamp object's ToDateTime method:ĭateTime dt = so.DeliveryDate.ToDateTime() So.DeliveryDate = Timestamp.FromDateTime(new DateTime(2020,4,3,0,0,0,DateTimeKind.Utc)) In the following example, I'm using the class' FromDateTime static method to convert April 4th, 2020 UTC into a Timestamp (Timestamps will only work with UTC coordinated times): I can, for example, set my DeliveryDate field using static methods built into the TimeStamp class.

DeliveryDate = 2 īecause this is a well known type, the gRPC tools generate helpful code for working with Timestamp fields. I can now use timestamp in my SalesOrder message, referencing it by its ProtoBuf namespace google.protobuf: Import 'google/protobuf/timestamp.proto' Here's what I need to import two well known types, timestamp and empty in my. proto file from the well known types repository.

More critically, the gRPC tools will generate the helpful code on any platform to work with those types (though here, of course, I'm only going to show how to use the types in C#).įor example, to store a date, you can import the timestamp.

If they don't, the documentation exists on the Internet. The benefit of using the well known types is interoperability: It's likely that business partners creating clients that use your services will know about and be able to use these types. Instead of defining a new type, all you have to do is import the type you need. The other solution is to take advantage of Google's predefined well known types. NET Core (and I understand that such people exist) won't be able to use your C# code. And, of course, anyone building an application who isn't using. business partners) won't know about your new type and will have to badger you to find out how to use your type. I think this is a great solution…provided you're working only with internal clients and you have a homogenous. Here's an article on how to define your own types. NET Core will take care of merging your partial class' code into the code generated by the gRPC tools. If you're careful about naming that partial class. You don't have to stop there: You can continue on to define a partial class containing helpful code to simplify manipulating data in messages that use your definition. Your definition for a decimal type might consist of just two integers: one that defines the number and the other that specifies how much of that number is to the right of the decimal. proto file where you want to use your new definition. One solution is to define your own data type in a. In addition, I'll show the solution to another problem: How do you define a service that doesn't return a result (well, sort of).

I mention those columns because in both of them I whined about how the Protocol Buffer (ProtoBuf) specification doesn't include some data types that I take for granted: date and decimal, to be precise (out of the box, ProtoBuf expects you to use the imprecise float type for data with decimals).Īs I said in the second column on importing/re-using data types, there are ways to deal with these missing data types and this column will walk you through all three. I followed that up with another column that showed how you can re-use and import definitions. In an earlier column, I described how to define the message formats that clients can use to communicate with your gRPC services.
