c# - C# possible to compare string[] to 4 other string[]?

Question

I've been looking around for a while now for some answers, but I cant find it anywhere.

I need a solution for this in C#:

if (stringer[1] == stringer[2]||stringer[3]||stringer[4]||stringer[5])
{

}

this obviously doesn't work in C#, so I need a way to do this.

thank you!

Answer 1

Try this:

if (stringer.Skip(1).Any(v => v.Equals(stringer[0])) {
    ...
}

This code compares every item in the stringer array from the second on to the initial item, returning true if the initial item is duplicated anywhere else in the array.

Answer 2

您必须单独比较每个项目，或使用上述 LINQ 解决方案。

if (stringer[1] == stringer[2] || stringer[1] == stringer[3] || 等等)

Answer 3

如果有一个字符永远不会出现在字符串中，您可以将其用作分隔符：

 ( "|" + stringer[2] + "|" + stringer[3] + "|" ).IndexOf( "|" + stringer[1] + "|" ) >= 0

丑陋，古老的技术。
