string[] drives = Environment.GetLogicalDrives(); string driveNames = String.Empty; foreach (string drive in drives) driveNames += drive.Substring(0,1); // Create regular expression pattern dynamically based on local machine information. string pattern = @"\\\" + Environment.MachineName + @...
For example, splitting a string on a single hyphen causes the returned array to include an empty string in the position where two adjacent hyphens are found. If a match is found at the beginning or the end of the input string, an empty string is included at the beginning or the end of...
a string, while metacharacters serve as an operator, allowing for more complex patterns to be created. even with just these two types of characters it is possible to create powerful patterns that can accurately search or replace parts of a text string. what are some common use cases for ...
{n}This operator matches the preceding character exactly n times. The expressiondrives{2}matches "drivess" but not "drive," "drives," "drivesss," or any number of trailing "s" characters. However, because "drivesssss" contains the stringdrivess, a match occurs on that string, so the li...
