Allow KeyValuePair<string, string>[] array = new[] { new("key1", value1), new("key2", value2) };
With introduction of new() expression (#100), the following:
IEnumerable<KeyValuePair<string, string>> Headers = new[]
{
new KeyValuePair<string, string>("Foo", foo),
new KeyValuePair<string, string>("Bar", bar),
}
can be simplified to:
IEnumerable<KeyValuePair<string, string>> Headers = new KeyValuePair<string, string>[]
{
new("Foo", foo),
new("Bar", bar),
}
but you still need to repeat the type following the field/property initializer. Closest you can get is something like:
IEnumerable<KeyValuePair<string, string>> Headers = new[]
{
new KeyValuePair<string, string>("Foo", foo),
new("Bar", bar),
}
For the sake of completeness, I'd suggest to also make new[] a target-typed expression,
IEnumerable<KeyValuePair<string, string>> Headers = new[]
{
new("Foo", foo),
new("Bar", bar),
}
The mechanics of such feature is similar to #2389 or #2460 where there are two source of type inference, the common type and the target-type.
Note: A list/dictionary literal feature would not supersede this proposal because in above examples there's no concrete collection type to infer.
