I have a textbox that has a value depends on the Path of the file after dragging the folder. the return value of dragged folder is "C:Program Files".
and I want to add the char "" on the textbox, but if I add that character, there is an error such as red line below my code, the example of a red line is when you misspelled a word in a document.

code:

txtResult.Text + "" + textFile + ".txt"

Question:

what is the main reason that this string value does have an error?

When inside a string the backslash character '', it is interpreted as an escape character.

In your case it's escaping the double quote, which is nesseccary when you want a double quote character inside a quoted string. However since you want the literal backslash, you should escape the backslash, which Means:

Use "\".

Now it will produce a single backslash.

Edit:

Another option is to use an @-quoted string, like this:

@""

Now you don't have to escape the character.

You may also use verbatim string: var path = @"C:Program Files";
