比较两个string数组的C＃

好的，所以这可能是一个基本的问题，但我将不胜感激。

假设我们有5个string数组：

string[] a = {"The","Big", "Ant"}; string[] b = {"Big","Ant","Ran"}; string[] c = {"The","Big","Ant"}; string[] d = {"No","Ants","Here"}; string[] e = {"The", "Big", "Ant", "Ran", "Too", "Far"}; 

有没有一种方法比较这些string彼此没有在C＃中循环，只有一个和C会产生布尔真正？ 换句话说，所有的元素必须相同，数组必须是相同的大小？ 再次，如果可能，不使用循环。 提前致谢！

Answer 1

你可以使用Linq：

 bool areEqual = a.SequenceEqual(b); 

Answer 2

尝试使用Enumerable.SequenceEqual ：

 var equal = Enumerable.SequenceEqual(a, b); 

Answer 3

如果你想一口气把它们全部比较：

 string[] a = { "The", "Big", "Ant" }; string[] b = { "Big", "Ant", "Ran" }; string[] c = { "The", "Big", "Ant" }; string[] d = { "No", "Ants", "Here" }; string[] e = { "The", "Big", "Ant", "Ran", "Too", "Far" }; // Add the strings to an IEnumerable (just used List<T> here) var strings = new List<string[]> { a, b, c, d, e }; // Find all string arrays which match the sequence in a list of string arrays // that doesn't contain the original string array (by ref) var eq = strings.Where(toCheck => strings.Where(x => x != toCheck) .Any(y => y.SequenceEqual(toCheck)) ); 

返回两个匹配（你可能扩大这个排除已经匹配的项目，我想）

Answer 4

  if (a.Length == d.Length) { var result = a.Except(d).ToArray(); if (result.Count() == 0) { Console.WriteLine("OK"); } else { Console.WriteLine("NO"); } } else { Console.WriteLine("NO"); }
