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.

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"

try this code,

str.TrimEnd(';');

Usually I just delete the last character after the line is formed.

I use a StringBuilder and just do:

var builder = new StringBuilder();
// ...
// add the text
// ...
builder.Length--;

This way I can avoid the string copy.
