To split a string by another string separator, we can use Split
function of C#.
Example code
In below example, we are converting a comma-separated string into a list of string.
string nodeUrls = "127.0.0.1:2222,127.0.0.1:2223,127.0.0.1:2224";
List<string> nodeList = nodeUrls.Split(new string[] { "," }, StringSplitOptions.None).ToList();
