Value Property (SQLiteBlob)
This code fragment downloads a BLOB field from a table to a file.
Value property is initialized by calling
SQLiteDataReader.GetSQLiteBlob method and then written to a stream.
SQLiteBlob myBlob = myReader.GetSQLiteBlob(myReader.GetOrdinal("Picture"));
if(!myBlob.IsNull)
{
string FN = myReader.GetString(myReader.GetOrdinal("PicName"));
FileStream fs = new FileStream("D:\\Tmp\\"+FN+".bmp", FileMode.Create);
fs.Write(myBlob.Value,0,(int)myBlob.Length);
fs.Close();
Console.WriteLine(FN+" downloaded.");
}
Dim myBlob As SQLiteBlob = myReader.GetSQLiteBlob(myReader.GetOrdinal("Picture"))
If Not myBlob.IsNull Then
Dim FN As String = myReader.GetString(myReader.GetOrdinal("PicName"))
Dim fs As FileStream = New FileStream("D:\Tmp\" + FN + ".bmp", FileMode.Create)
fs.Write(myBlob.Value, 0, Convert.ToInt32(myBlob.Length))
fs.Close()
Console.WriteLine(String.Concat(FN, " downloaded."))
End If
