int result = Array.BinarySearch(list.ToArray(), typedString, StringComparer.OrdinalIgnoreCase);

string [] lines = {"text1", "text2", "etc"};

bool bFound = lines.Any(x => x == "Your string to be searched");

如果搜索的字符串与数组'lines'中的任何元素匹配，则bFound设置为true。

你可以这样做:

string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };
foreach (string x in stringArray)
{
    if (stringToCheck.Contains(x))
    {
        // Process...
    }
}

也许你正在寻找一个更好的解决方案……参考Anton Gogolev使用LINQ的答案。

演示了三个选项。我认为第三条是最简洁的。

class Program {
    static void Main(string[] args) {
    string req = "PUT";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("one.1.A");  // IS TRUE
    }
    req = "XPUT";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("one.1.B"); // IS TRUE
    }
    req = "PUTX";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("one.1.C");  // IS TRUE
    }
    req = "UT";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("one.1.D"); // false
    }
    req = "PU";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("one.1.E"); // false
    }
    req = "POST";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("two.1.A"); // IS TRUE
    }
    req = "ASD";
    if ((new string[] {"PUT", "POST"}).Any(s => req.Contains(s))) {
        Console.WriteLine("three.1.A");  // false
    }


    Console.WriteLine("-----");
    req = "PUT";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("one.2.A"); // IS TRUE
    }
    req = "XPUT";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("one.2.B"); // false
    }
    req = "PUTX";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("one.2.C"); // false
    }
    req = "UT";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("one.2.D"); // false
    }
    req = "PU";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("one.2.E"); // false
    }
    req = "POST";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("two.2.A");  // IS TRUE
    }
    req = "ASD";
    if (Array.IndexOf((new string[] {"PUT", "POST"}), req) >= 0)  {
        Console.WriteLine("three.2.A");  // false
    }

    Console.WriteLine("-----");
    req = "PUT";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("one.3.A"); // IS TRUE
    }
    req = "XPUT";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("one.3.B");  // false
    }
    req = "PUTX";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("one.3.C");  // false
    }
    req = "UT";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("one.3.D");  // false
    }
    req = "PU";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("one.3.E");  // false
    }
    req = "POST";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("two.3.A");  // IS TRUE
    }
    req = "ASD";
    if ((new string[] {"PUT", "POST"}.Contains(req)))  {
        Console.WriteLine("three.3.A");  // false
    }

    Console.ReadKey();
    }
}

试试这个。没有任何循环的需要。

string stringToCheck = "text1";
List<string> stringList = new List<string>() { "text1", "someothertext", "etc.." };
if (stringList.Exists(o => stringToCheck.Contains(o)))
{

}

Try:

String[] val = { "helloword1", "orange", "grape", "pear" };
String sep = "";
string stringToCheck = "word1";

bool match = String.Join(sep,val).Contains(stringToCheck);
bool anothermatch = val.Any(s => s.Contains(stringToCheck));
