我认为我的代码应该使ViewBag.test属性等于"No Match",但它会抛出一个InvalidOperationException.

为什么是这样？

string str = "Hello1,Hello,Hello2";
string another = "Hello5";
string retVal = str.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)
                   .First(p => p.Equals(another));
if (str == another)
{
   ViewBag.test = "Match";
}
else
{
   ViewBag.test = "No Match"; //this does not happen when it should
}
