我如何检查，如果一个值是一个数组在C＃？

How do I check if a value is in an array in C#?

像，我想创建与打印机名称列表的数组。

Like, I want to create an array with a list of printer names.

这些将被馈送到一个方法，该方法将着眼于依次在每个字符串，如果该字符串是一样在数组中的值，执行该操作。

These will be fed to a method, which will look at each string in turn, and if the string is the same as a value in an array, do that action.

例如：

string[] printer = {"jupiter", "neptune", "pangea", "mercury", "sonic"};
foreach (p in printer)
{
   PrinterSetup(p);

}

这些是打印机的名称，它们被馈送到PrinterSetup方法

These are the names of the printers, they are being fed to the PrinterSetup method.

PrinterSetup看起来有几分像这样（一些伪code）：

PrinterSetup will look sorta like this (some pseudocode):

public void PrinterSetup(printer)
{
   if (printer == "jupiter") 
   {
      Process.Start("BLAH BLAH CODE TO ADD PRINTER VIA WINDOWS EXEC"");
   }
}

我如何格式化如果（打印机==朱庇特）{的方式，C＃可以识别？

How do I format if (printer == "jupiter") { in a way that C# can recognize?

推荐答案

添加必要的命名空间

using System.Linq;

然后你可以使用LINQ 包含（）方法

string[] printer = {"jupiter", "neptune", "pangea", "mercury", "sonic"};
if(printer.Contains("jupiter"))
{
    Process.Start("BLAH BLAH CODE TO ADD PRINTER VIA WINDOWS EXEC"");
}
