Testing an Entity Framework database connection
Are you just wanting to see if the DB connection is valid? If so take a look at the
using (DatabaseContext dbContext = new DatabaseContext()){ dbContext.Database.Exists();}http://msdn.microsoft.com/en-us/library/gg696617(v=vs.103).aspx
and for checking if a server machine is up, DB server or web services server , try this:
public PingReply Send( string hostNameOrAddress )
The solution as @Danilo Breda pointed out is to call the DbContext.Database.Connection.Open()
It is tested with EF6.
My implementaion:
public static bool CheckConnection() { try { MyContext.Database.Connection.Open(); MyContext.Database.Connection.Close(); } catch(SqlException) { return false; } return true; }
In EntityFramework Core you can simply call: Database.CanConnect();.
(using EF Core 2.2.1)
Summary: Determines whether or not the database is available and can be connected to.
Note that being able to connect to the database does not mean that it is up-to-date with regard to schema creation, etc.
