[Unity C#] Split string array and add each string to list

For example, pathArray merged image files.
string pathArray = "file:///var/mobile/Media/DCIM/184APPLE/IMG_4155.PNG:file:///var/mobile/Media/DCIM/184APPLE/IMG_4156.PNG:file:///var/mobile/Media/DCIM/184APPLE/IMG_4157.PNG";

// String split with specific character(ex, ':')
void ListImagePath (string pathArray) {
    // Initialize image list
    List<string> imageList = new List<string> ();
    // Separate pathArray strings to splitString array.
    string[] splitString = pathArray.Split (':');

    foreach (string imagePath in splitString) {
        // add each image path to image list.
        imageList.Add (imagePath);
    }
}

Then each imagePath is 

imagePath = "file:///var/mobile/Media/DCIM/184APPLE/IMG_4155.PNG";

imagePath = "file:///var/mobile/Media/DCIM/184APPLE/IMG_4156.PNG";

imagePath = "file:///var/mobile/Media/DCIM/184APPLE/IMG_4157.PNG";

Image List will be added each imagePath string.

Before using simpleJSON, I used this method for splitting iOS media paths in MobileMediaPicker.
