C# split string and remove empty string

To split a string and remove empty strings in C#, you can use the Split method and pass StringSplitOptions.RemoveEmptyEntries as the second parameter. Here's an example:

string input = "this,,is,a,,test"; string[] parts = input.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

This will split the string into an array of strings, removing any empty strings that result from consecutive commas. In this example, the parts array will contain four strings: "this", "is", "a", and "test".
