拆分字符串并排除上次拆分

Question

Is there anyway for me to split a string and exclude the last split?

My data looks like this: data1,data2,data3, and so if I split the element the last element in the array will be empty, so I would just prefer to exclude it from the split.

Right now I have this:

serialNumbers = delimitedSerials.ToString().Split(',');

Granted I know I can just leave it and in my for loop just know to skip the last element, but was wondering if there was a simple way to just exclude it at the time of splitting.

Answer 1

您可以使用 StringSplitOptions 参数拆分它：

data.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

Answer 2

Below code has a Linq where clause to exclude the empty data

string input ="data1,data2,data3,";

var output = input.Split(',').Where(value => !string.IsNullOrEmpty(value));

foreach(string data in output)
    Console.WriteLine(data);
