如何比较字符串数组的值？
如何比较字符串数组的值？
提问于 2017-07-06 14:22:17
我已经声明了一个字符串数组，我想将其与用户指定的名称进行比较，
string[] MasterList = new string[] {
"Askay", "Puram", "Raman", "Srinivasa",
"Gopal", "Rajesh", "Anju", "Nagara",
};
string YourName;
Console.WriteLine("Enter your name: ");
YourName = Console.ReadLine();
for(i=0; i<5; i++)
{
a = String.Compare(MasterList[i], YourName);
Console.WriteLine("Your name is not among the list")
}结果的输出不是我所期望的，有什么想法我可以怎么做吗？

bool found = false;
foreach (string s in MasterList)
{
if(s == YourName)
found = true;
}
if(found)
Console.WriteLine("Your name is among the list");
else
Console.WriteLine("Your name is not among the list");Stack Overflow用户

为什么不使用Contains方法呢？
首先在使用指令中添加以下行：
using System.Linq;然后，删除for循环并使用以下行：
if (!MasterList.Contains(YourName, StringComparer.OrdinalIgnoreCase))
{
Console.WriteLine("Your name is not among the list")

为什么不Contains？
string[] MasterList = new string[] {
"Askay", "Puram", "Raman", "Srinivasa",
"Gopal", "Rajesh", "Anju", "Nagara",
};
Console.WriteLine("Enter your name: ");
string YourName = Console.ReadLine();
// StringComparer.OrdinalIgnoreCase if you want to ignore case
// MasterList.Contains(YourName) if you want case sensitive
if (!MasterList.Contains(YourName, StringComparer.OrdinalIgnoreCase))
