Can this foreach be improved?

Question

This foreach is intended to look through a list and when a match is found it returns the next element. Can it be improved?

public static string GetCommandLineArg(string arg)
{
    var doreturn = false;

    foreach (var item in Environment.GetCommandLineArgs())
        if (doreturn)
            return item;
        else if (arg == item)
            doreturn = true;

    return null;
}

The part I am concerned with is the returning of the next item.

内部if语句杂乱无章，似乎不需要使用额外的变量。是否有一个简单的函数调用或属性可以与a foreach一起使用以返回下一个项目？

与Linq接触

public static string GetCommandLineArg(string arg)
{
    return Environment.GetCommandLineArgs().SkipWhile(x => x != arg).Skip(1).FirstOrDefault();
}
