How do I put { or } in verbatim string in C#?
using System;
class DoFile {
static void Main(string[] args) {
string templateString = @"
\{{0}\}
{1}
{2}
";
Console.WriteLine(templateString, "a", "b", "c");
}
}
I get error when I use '{' or '}' in verbatim string, I guess it's because '{' or '}' is used for parameter marking such as {0}, {1}, {2}. \{ doesn't work.
Unhandled Exception: System.FormatException: Input string was not in a correct format.

You just have to escape with double curly brackets..
{{ or }} respectively..
Something like below
string.Format("This is a format string for {0} with {{literal brackets}} inside", "test");
This is a format string for test with {literal brackets} inside
You put two like such {{ or }}.
There is nothing special about putting { and } in a string, they should not be escaped. Besides, the escape character \ has no effect in a @ delimited string.
To use literal { and } in the format for the String.Format method, you double them. So, your format string would be:
string templateString = @"
{{{0}}}
{1}
{2}
";
