How to Fix

Addressing MySQL Date/Time Conversion Error to System.DateTime

When retrieving data from a MySQL database, encountering the error "Unable to convert MySQL date/time value to System.DateTime" is common. This occurs due to the inherent differences in how MySQL stores and interprets date/time values compared to System.DateTime in .NET.

To resolve this issue, you need to modify your database connection string. By adding the "Convert Zero Datetime=True" parameter to the connection string, you instruct the MySQL driver to convert any zero-value date/time fields in the database to the System.DateTime equivalent, which is January 1, 0001, 12:00:00 AM.

For example, a connection string that includes this parameter might look like this:

server=localhost;User Id=root;password=mautauaja;Persist Security Info=True;database=test;Convert Zero Datetime=True

Incorporating this parameter ensures that when retrieving date/time values from your MySQL database, they will be correctly converted to the System.DateTime format without triggering the conversion error.
