Unrecognized excape sequence

Solution

You need to use double backslashes (\\) or a verbatim string literal (@ prefix) to correctly format the file path.

Option 1: Escape Backslashes

attachment.FileName = "C:\\10.0.1.10\\SAP_Attachments\\O_204673_20250314_205951";

Option 2: Use a Verbatim String Literal

attachment.FileName = @"C:\10.0.1.10\SAP_Attachments\O_204673_20250314_205951";

Note

Your original string starts with @, which is incorrect syntax. If you meant to use a verbatim string, you should write:

attachment.FileName = @"\\10.0.1.10\SAP_Attachments\O_204673_20250314_205951";

This correctly represents a UNC (Universal Naming Convention) path for a network share.

Hello Ramco,

You need to add a Verbatim String (@ before the string), just check on this it should resolve your issue

attachment.FileName = @"\\10.0.1.10\SAP_Attachments\O_204673_20250314_205951";

It seems like the error you are encountering is related to an unrecognized escape sequence in C# code. In the provided code snippet:

attachment.FileName = "@10.0.1.10\SAP_Attachments\O_204673_20250314_205951");

The issue lies with the backslashes used in the file path. In C# strings, backslashes are used to escape characters, meaning they are interpreted as special characters. If you want to include a backslash as a literal character in a string, you need to escape it by using another backslash before it.

To resolve the error, you can correct the file path string by escaping the backslashes properly, like this:

attachment.FileName = "@10.0.1.10\\SAP_Attachments\\O_204673_20250314_205951");

By doubling the backslashes, you are telling the C# compiler to treat them as literal backslashes in the string. This adjustment should resolve the "Unrecognized escape sequence" error you are facing.
