EndBackup Method

Ends an asynchronous invocation of the Backup method.

Syntax

Visual Basic
C#

public void EndBackup( 
   IAsyncResult result
)

'Declaration
 
Public Sub EndBackup( _
   ByVal result As IAsyncResult _
)

Parameters

result: The System.IAsyncResult returned by BeginBackup.

Remarks

The function ends an asynchronous backup that is started with BeginBackup. A pair of asynchronous functions (BeginBackup and EndBackup) can be used instead of the synchronous function Backup to gain more performance and flexibility in your application.

Example

This sample demonstrates performing async backup and restore operations.

csharp

public void DumpIt(PgSqlConnection conn)
{
        conn.Open();
        PgSqlDump pgSqlDump = new PgSqlDump();
        pgSqlDump.Connection = conn;
        pgSqlDump.Schema = "public";
        pgSqlDump.Tables = "dept;emp";
        pgSqlDump.IncludeDrop = true;
        IAsyncResult Result = pgSqlDump.BeginBackup("d:\\dump.dmp");
        while (!Result.IsCompleted)
        {
                Console.Write(".");
                //Perform here any operation you need
        }
        pgSqlDump.EndBackup(Result);
        Console.WriteLine("Dumped.");
        conn.Close();
}

public void UnDumpIt(PgSqlConnection conn)
{
        conn.Open();
        PgSqlDump pgSqlDump = new PgSqlDump();
        pgSqlDump.Connection = conn;
        IAsyncResult Result = pgSqlDump.BeginRestore("d:\\dump.dmp");
        while (!Result.IsCompleted)
        {
                Console.Write(".");
                //Perform here any operation you need
        }
        pgSqlDump.EndRestore(Result);
        Console.WriteLine("Restored.");
        conn.Close();
}
