Question

What I have is a C# windows app that reads a bunch of SQL tables and creates a bunch of queries based on the results. What I’m having a small issue with is the final “,” on my query

This is what I have

ColumnX,

from

I need to read the entire file, write out exactly what is in the file and just replace the last , before the from with nothing.

I tried .replace(@",\n\nfrom),(@"\n\nfrom) but it’s not finding it. Any help is appreciated.

Example:

ColumnX,

from

Result:

ColumnX

from

The line break is most likely the two character combination CR + LF:

.replace(",\r\n\r\nfrom","\r\n\r\nfrom")

If you want the line break for the current system, you can use the Environment.NewLine constant:

.replace(","+Environment.NewLine+Environment.NewLine+"from",Environment.NewLine+Environment.NewLine+"from")

Note that the @ in front of a string means that it doesn’t use backslash escape sequences, but on the other hand it can contain line breaks, so you could write it in this somewhat confusing way:

str = str.replace(@",

from", @"

from");
