Recording application operation logs can use databases, text files, xml files, etc. What I introduce here is the use of XML files to record operation logs.
I think using XML to record operation logs has the following advantages:
1. It does not occupy database space, and historical operation logs can be deleted arbitrarily.
2. DataTable can easily read XML files, and DataTable can also be easily saved as XML files.
3. It is convenient to view the log. You can directly open the XML file to view it, or you can read it into the DataTable and then view it through the program.
The method of using XML files to record operation logs in VS2005 is as follows:
1. Create a data set: JobLogDataSet.xsd
This includes: TraceLevel (log type), User (user), DateTime (operation Time), Module (module), Function (function), Message (message) 6 fields.
If it’s not enough, add more by yourself, where TraceLevel (log type) refers to Info, Warning, Error, Trance, Off.
2. Create a log type
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
|
2. How to write a log
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
JobLogDataSet.JobLogDataTable t = new JobLogDataSet .JobLogDataTable();
1 2 3 4 5 |
|

|
1 2 3 4 5 6 7 8 9 |
|
1 2 3 4 5 6 |
|
3. How to read the log
1 2 3 4 5 6 7 8 9 10 11 12 |
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |

4. Where you need to write a log, just call the WriteLog method directly.
