分割字符串和CSV C＃

Question

I have written an exporter that exports strings to .csv

Thing is, some of these strings have commas in already:

2 CAR MODELS, 5 TEAMS,2 CAR MODELS, 5 TEAMS

You see that the commas added in the strings by hand have one white space after them. The one I added has no whitespace.

I have written code to read the string and split it:

while ((line = stringReader.ReadLine()) != null)
        {
            // split the string at each comma
            string[] split = line.Split(new char[] { ',' });

What i need is for the string to split at ',' and NOT at ', '.

Any ideas?

I cant use any third party code like this:

Answer 1

您可以使用TextFieldParser它位于Microsoft.VisualBasic.FileIO命名空间中，因此不能位于“ thirdparty”中。

Answer 2

You might consider using Regex.Split(String arg1, String arg2) . It should allow you to split a string according to a regular expression.

You can then use a regex like this:

,[^\s]+

This should allow you to split values which have a comma but are not followed with one or more spaces.

Answer 3

You can do this with Regex.Split in the System.Text.RegularExpressions namespace.
