public:
virtual property System::String ^ Source { System::String ^ get(); };C#
public override string Source { get; }member this.Source : stringPublic Overrides ReadOnly Property Source As String產生錯誤的 ODBC 驅動程式名稱。
下列範例會顯示Message集合中OdbcErrorCollection第一個 OdbcError 的、 Source和 NativeError 屬性。
C#
public void ShowOdbcException()
{
string mySelectQuery = "SELECT column1 FROM table1";
OdbcConnection myConnection =
new OdbcConnection("DRIVER={SQL Server};SERVER=MyServer;Trusted_connection=yes;DATABASE=northwind;");
OdbcCommand myCommand = new OdbcCommand(mySelectQuery,myConnection);
try
{
myCommand.Connection.Open();
}
catch (OdbcException e)
{
string errorMessage = "Message: " + e.Message + "\n" +
"Source: " + e.Source;
System.Diagnostics.EventLog log = new System.Diagnostics.EventLog();
log.Source = "My Application";
log.WriteEntry(errorMessage);
Console.WriteLine("An exception occurred. Please contact your system administrator.");
}
}
Public Sub ShowOdbcException()
Dim mySelectQuery As String = "SELECT column1 FROM table1"
Dim myConnection As New OdbcConnection _
("DRIVER={SQL Server};SERVER=MyServer;Trusted_connection=yes;DATABASE=northwind;")
Dim myCommand As New OdbcCommand(mySelectQuery, myConnection)
Try
myCommand.Connection.Open()
Catch e As OdbcException
Dim errorMessage As String = "Message: " & e.Message & vbCrLf & _
"Source: " & e.Source
Dim log As New System.Diagnostics.EventLog()
log.Source = "My Application"
log.WriteEntry(errorMessage)
Console.WriteLine("An exception occurred. Please contact your system administrator.")
End Try
End Sub
這是集合中Errors第一個 OdbcError 屬性的包裝函Source式。
