我在下面的代码中遇到了一个高验证码扫描问题。我需要做哪些改变来解决它。
private OleDbConnection importFileConnection;
private OleDbConnection ImportFileConnection
{
get
{
if (importFileConnection == null)
{ importFileConnection = new OleDbConnection(this.ConnectionString);
//getting scan issue in this line. }
//importFileConnection.Open();
return importFileConnection;
}
}
private string ConnectionString
{
get { return string.Format(ImportExportData.Default.ConnectionString, this.ServerFileName); }
}
