How To Customize InnerException.Message For System.Data.UpdateException In ASP.NET

I am adding data to a database table using Entity Framework. When adding a duplicate Primary Key I get an exception in InnerException.Message that reads "Violation of PRIMARY KEY constraint 'PK_StudentID'. Cannot insert duplicate key in object 'dbo.Students'. The statement has been terminated. "However, what I want to do is to rephrase this error message for the end user, but also save this exact message with the table name and column name to my logs for later. Essentially, I want to rephrase the error message to "You cannot have a duplicate entry for Student Identification Number. Please enter a new value."I have tried to inherit from System.Data.UpdateException and put an if check to see what the innerexception.message reads, and then change it accordingly. That did not work.
