From 9629797331e6859ce68c5489fc690d3526a3915a Mon Sep 17 00:00:00 2001 From: Jon Skeet Date: Thu, 30 Jul 2015 09:29:52 +0100 Subject: Well-known type operations for Timestamp and Duration (but not JSON formatting). While I've provided operators, I haven't yet provided the method equivalents. It's not clear to me that they're actually a good idea, while we're really targeting C# developers who definitely *can* use the user-defined operators. --- .../WellKnownTypes/DurationTest.cs | 104 +++++++++++++++++++++ .../WellKnownTypes/TimestampTest.cs | 84 +++++++++++++++++ 2 files changed, 188 insertions(+) create mode 100644 csharp/src/Google.Protobuf.Test/WellKnownTypes/DurationTest.cs create mode 100644 csharp/src/Google.Protobuf.Test/WellKnownTypes/TimestampTest.cs (limited to 'csharp/src/Google.Protobuf.Test/WellKnownTypes') diff --git a/csharp/src/Google.Protobuf.Test/WellKnownTypes/DurationTest.cs b/csharp/src/Google.Protobuf.Test/WellKnownTypes/DurationTest.cs new file mode 100644 index 00000000..36012e63 --- /dev/null +++ b/csharp/src/Google.Protobuf.Test/WellKnownTypes/DurationTest.cs @@ -0,0 +1,104 @@ +#region Copyright notice and license +// Protocol Buffers - Google's data interchange format +// Copyright 2015 Google Inc.
