When I have three double quotes is call me I have Syntax error, ',' expected I try with four double quotes, with slash but again I have this error. I know for escaping double quotes is need two double quotes. But for my case is not working.

Answer 1

As per msdn, you will either use @"" or escape with \\"

Answer 2

For what you are trying to achieve, the best approach is using string.Format , as follows:

string.Format(@"""Air Temperature sensor "" 20, {0}, 24 "" {1:yyyy-MM-dd hh:mm:ss}", measure, this.time);

You don't need to build the date taking the single properties when .NET can format it for you.
