The TruncateFilename method is a static extension method in the SandboxSystemExtensions class. It is used to truncate a given string to a specified maximum length, appending a specified string if truncation occurs. This is particularly useful for shortening filenames while preserving a recognizable part of the original name.
To use the TruncateFilename method, call it on a string object, passing the maximum length and the appendage string as parameters. The method will return a new string that is truncated to the specified length, with the appendage added if truncation was necessary.
// Example usage of TruncateFilename string filename = "very_long_filename_that_needs_truncation.txt"; int maxLength = 20; string appendage = "..."; string truncatedFilename = SandboxSystemExtensions.TruncateFilename(filename, maxLength, appendage); // Output: "very_long_filename..."
