C# 有没有像 Swift 那样的转义封包（escaping closures）？

[ShikiSuen]

就像这种的： https://www.oulub.com/docs/swift/zh-tw/Closures.html#ID546

搞出來了。

```swift
class test {
static func someFunctionWithNonescapingClosure(closure: (String) -> Void) {
let testString: String = "123"
closure(testString)
}

static func usage() {
someFunctionWithNonescapingClosure() { newString in
print(newString)

}
}
}

test.usage()
```


```csharp
using System;

class Untitled
{
static void someFunctionWithNonescapingClosure(Action<string> closure) {
string testString = "123";
closure(testString);
}

static void usage() {
// 備好動喔容器
Action<string> testStr = Console.WriteLine;
someFunctionWithNonescapingClosure(testStr);
}
static void Main(string[] args)
{
usage();
}
}
```
