这个方法返回什么？ （C＃）

Question

Not so long ago I moved from Java to C# and I'm still learning and today I bumped into this in some code.

public async Task<(decimal Price, string NativeCurrency)> GetCurrentStockPrice(string ticker)

I'm wondering just based on the method signature what exactly does this method return? Does it return two values?

Answer 1

This returns a tuple of (decimal Price, string NativeCurrency)

So you would call

var currentStockPrice = await GetCurrentStockPrice("USD") //or whatever the ticket string needs to be instead of "USD"

and

currentStockPrice.Item1 is decimal Price
currentStockPrice.Item2 is string NativeCurrency
