Repairs a corrupted database.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in

public void Repair (
	string connectionString,
	RepairOption options
public void Repair (
	String connectionString, 
	RepairOption options
public function Repair (
	connectionString : String, 
	options : RepairOption
Not applicable.



The local connection string to the database.


The RepairOption to use when repairing the database.

If the repair method is invoked by using the RepairOption's DeleteCorruptedRows value, all corrupted pages are discarded from the database. This may result in significant data loss, but the data recovered using this option should be free from corruption.

If the repair method is invoked by using the RepairOption's RecoverCorruptedRows value, the database will attempt to read data from the corrupted pages. This potentially results in more data being recovered, but this option does not guarantee that the data recovered will be free of corruption.

SqlCeEngine engine = new SqlCeEngine("Data Source = AdventureWorks.sdf");

// Specify null destination connection string for in-place repair
engine.Repair(null, RepairOption.DeleteCorruptedRows);
