Logging properly handles arrays, but not within tuples #63165
Description
Description
When logging with Microsoft.Extensions.Logging, arrays (or other enumerables) are recognized and emitted properly when they're simple parameters directly referenced by placeholders in the message. However, when the placeholder refers to a value tuple containing an array, ToString is called on the array, yielding the wrong representation.
Serilog properly handles this scenario.
Reproduction Steps
var loggerFactory = LoggerFactory.Create(builder =>
{
builder.AddSimpleConsole();
builder.AddProvider(new SerilogLoggerProvider());
});
// Shows 1, 2, 3 - OK
logger.LogInformation("Simple array: {Array}", new[] { 1, 2, 3 });
// Shows (System.Int32[], foo)
logger.LogInformation("Array in tuple: {Tuple}", (Array: new[] { 1, 2, 3 }, SomethingELse: "foo"));Expected behavior
Something like the following:
Simple array: 1, 2, 3
Array in tuple: ((1, 2, 3), foo)
Serilog outputs:
Simple array: [1, 2, 3]
Array in tuple: [[1, 2, 3], "foo"]
Actual behavior
ToString is called on the array:
Simple array: 1, 2, 3
Array in tuple: (System.Int32[], foo)
