c# check substring in a string code example
Example 1: check if string is in string[] c#
string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };
foreach (string x in stringArray)
{
if (x == stringToCheck)
{
}
}
Example 2: c# check if string contains value
string s1 = "The quick brown fox jumps over the lazy dog";
string s2 = "fox";
bool b = s1.Contains(s2);
Console.WriteLine("'{0}' is in the string '{1}': {2}",
s2, s1, b);
if (b) {
int index = s1.IndexOf(s2);
if (index >= 0)
Console.WriteLine("'{0} begins at character position {1}",
s2, index + 1);
}
