Example

[Visual Basic, C#, C++] The following example displays each SqlError within the SqlErrorCollection collection.

[Visual Basic] 
Public Sub DisplaySqlErrors(myException As SqlException)
    Dim i As Integer
    For i = 0 To myException.Errors.Count - 1
        MessageBox.Show("Index #" & i & ControlChars.NewLine & _
                        "Error: " & myException.Errors(i).ToString() & ControlChars.NewLine)
    Next i
End Sub 'DisplaySqlErrors

[C#] 
public void DisplaySqlErrors(SqlException myException) 
 {
    for (int i=0; i < myException.Errors.Count; i++)
    {
       MessageBox.Show("Index #" + i + "\n" +
            "Error: " + myException.Errors[i].ToString() + "\n");
    }
 }

[C++] 
public:
void DisplaySqlErrors(SqlException* myException) 
 {
    for (int i=0; i < myException->Errors->Count; i++)
    {
       MessageBox::Show(String::Format( S"Index #{0}\nError: {1}\n",
          __box(i), myException->Errors->Item[i] ));
    }
 }
