- When counting the instances of a string or character in another, we used the Split() method with a character passed as argument (refresher code below), and a regular expression pattern passed to Regex.Matches(), and counting the matches by measuring the length of the returned array.
// Split a string with a character:
string str = "I learn C#";
string wordCount = str.Split(' ').Length.ToString();
MessageBox.Show("There are " +wordCount+ " words in that sentence");
- Define a multi-character string separator as an array element to pass to overloaded Split() :
string[] sep = new string[] {"-|-"}; // Three-character separator - Now pass it as you would a regular character argument:
// Values are separated with our three characters:
string data = "223-|-19-|-57-|-TestFile.txt";
// Extract individual settings from our array:
string[] settings = data.Split(sep, StringSplitOptions.None);
Note: "StringSplitOptions.None" instructs .NET to include empty string elements in returned value.
- You can combine this into a one-line statement with the separator as anonymous string:
string[] settings = data.Split(new string[] {"-|-"}, StringSplitOptions.None);
