Remove specific unicode character in the string in C#

Question

I am trying to remove specific unicode character in my string. Say we have below code .

public static string RemoveVerticalLine(this string source, char nil = ' ')
        {
            var s = '\u+007C';
            return new string(source.Select(c => c == s ? nil : c).ToArray());
        }

In the sample. I tried to remove the U+007c(Vertical Line). But I don't know why VS tell me error too many characters in character literal. Did I missed something?

That isn't how C# escape sequences work.

You need to write '\u007c'.

Or just use the actual character: '|'.

@Joe.wang: That's just the convention used when talking about Unicode code points. It has nothing to do with C# syntax. learn.microsoft.com/en-us/dotnet/csharp/programming-guide/…
