I am using an array within a C# program as follows:
开发者_开发技巧char[] x = {'0','1','2'};
string s = "010120301";
foreach (char c in s)
{
// check if c can be found within s
}
How do I check each char c to see if it is found within the character array x?
if (x.Contains(c))
{
//// Do Something
}
Using .NET 3.0/3.5; you will need a using System.Linq;
You could use Array.IndexOf method:
if (Array.IndexOf(x, c) > -1)
{
// The x array contains the character c
}
If I understood correctly, you need to check if c is in x. Then:
if(x.Contains(c)) { ... }
string input = "A_123000544654654";
string pattern = "[0-9]+";
System.Text.RegularExpressions.Regex.IsMatch(input, pattern);
