Recalculates the checksums for each page in the database and compares the new checksums to the expected values.
Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in System.Data.SqlServerCe.dll)
Syntax
'Declaration
Public Function Verify As Boolean
'Usage
Dim instance As SqlCeEngine
Dim returnValue As Boolean
returnValue = instance.Verify()
public bool Verify()
public:
bool Verify()
member Verify : unit -> bool
public function Verify() : boolean
Return Value
Type: System.Boolean
True if the checksums match and there is no database corruption; otherwise, false.
Remarks
If this method returns false, the database is corrupt, and your application should call the Repair method to correct the problem.
Note
False is also returned if there is a failure connecting to the database. Scenarios include an incorrect password, or the database file is inaccessible.
Examples
Dim engine As New SqlCeEngine("Data Source = AdventureWorks.sdf")
If False = engine.Verify() Then
MessageBox.Show("Database is corrupted.")
engine.Repair(Nothing, RepairOption.RecoverCorruptedRows)
End If
SqlCeEngine engine = new SqlCeEngine("Data Source = AdventureWorks.sdf");
if (false == engine.Verify())
{
MessageBox.Show("Database is corrupted.");
engine.Repair(null, RepairOption.RecoverCorruptedRows);
}
