| as pattern when using split

string input = @"12.2.2010|7";   
string pattern = @"|";

foreach (string result in Regex.Split(input, pattern)) 
{
   Console.WriteLine("'{0}'", result);
}

i want to use | as patter but开发者_Go百科 becouse | means or i can't get 12.2.2010. How can i use | like pattern? I try to use ~ but is the same.

Try to escape the | like this

string pattern = @"\|";

In a regular expression, if you want to match a literal |, you need to escape it with a backslash, like so:

string pattern = @"\|";

The character | has a special meaning in a regular expression, which means you have to escape it with a \ like so:

string pattern = @"\|";
