Question

Well I have export to CSV script.

I export list of struct. I write with help of StringWriter. In struct field array foreach cycle I iterate through all properties and after every property I put ‘;’. In the end of line I put WriteLine().

So as output I have:

value1;value2;value3;

And I want:

value1;value2;value3

The question is : how to get what I want from what I get, or based on what I’v already made.

I have 3 ideas right now:

1. The last 2 symbols in line should be something like “;\r(\n)” So replace this combination with nothing.
2. Check if the property is last.
3. Trim last(before newline) symbol in each row.

Answer 1

Use String.Join to form each line for your output. It prevents you from having to check which term is last.

var values = { "value1", "value2", "value3" };

string line = string.Join(";", values);

line will be

"value1;value2;value3"
