Question

I need to do some modifications on dynamically generated strings;

String Example

Products [279] Electric Paint Sprayer [21] Airbrush Equipment [109] Spray Tanning Equipment [23] Mini Air Compressor [33] Sand blasting gun [5] Paint Tank [9] Air Spray Gun [26] Pneumatic tools/Air tools [26] Tire Inflating gun [10] Air Riveter [6] Hand Tools [7] Comb/Hair Brush [4]

I want to remove “Products [279]” from the beginning (always the same except the numbers) and replace the rest of the string like this “Electric Paint Sprayer [21] – Airbrush Equipment [109] – …”

Answer 1

Demo

String sample = @"Products [279] Electric Paint Sprayer [21] Airbrush Equipment [109] Spray Tanning Equipment [23] Mini Air Compressor [33] Sand blasting gun [5] Paint Tank [9] Air Spray Gun [26] Pneumatic tools/Air tools [26] Tire Inflating gun [10] Air Riveter [6] Hand Tools [7] Comb/Hair Brush [4]";

// Remove "Products [#] "
sample = Regex.Replace(sample, @"^Products \[\d+\]\s*", String.Empty);

// Add hyphens
sample = Regex.Replace(sample, @"(\[\d+\])(?=\s*\w)", @"$1 - ");
// the (?=\s*\w) makes sure we only add a hyphen when there's more information
// ahead (and not a hyphen to the end of the string)

Outcome:

Electric Paint Sprayer [21] – Airbrush Equipment [109] – Spray Tanning Equipment [23] – Mini Air Compressor [33] – Sand blasting gun [5] – Paint Tank [9] – Air Spray Gun [26] – Pneumatic tools/Air tools [26] – Tire Inflating gun [10] – Air Riveter [6] – Hand Tools [7] – Comb/Hair Brush [4]
