Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

Syntax

'Declaration
<DefaultMemberAttribute("Item")> _
Public NotInheritable Class SqlCeErrorCollection
    Implements ICollection, IEnumerable

[DefaultMemberAttribute("Item")] 
public sealed class SqlCeErrorCollection : ICollection, IEnumerable

[DefaultMemberAttribute(L"Item")] 
public ref class SqlCeErrorCollection sealed : ICollection, IEnumerable

/** @attribute DefaultMemberAttribute("Item") */ 
public final class SqlCeErrorCollection implements ICollection, IEnumerable

DefaultMemberAttribute("Item") 
public final class SqlCeErrorCollection implements ICollection, IEnumerable

Remarks

This class is created by SqlCeException to collect instances of the SqlCeError class. SqlCeErrorCollection always contains at least one instance of the SqlCeError class.

Example

The following example displays each SqlCeError within the SqlCeErrorCollection collection.

Public Sub DisplaySqlCeErrors(ByVal errorCollection As SqlCeErrorCollection)

    Dim err As SqlCeError
    Dim bld As New StringBuilder()

    For Each err In errorCollection
        bld.Append((ControlChars.Cr & " Error Code: " & err.HResult.ToString("X")))
        bld.Append((ControlChars.Cr & " Message   : " & err.Message))
        bld.Append((ControlChars.Cr & " Minor Err.: " & err.NativeError))
        bld.Append((ControlChars.Cr & " Source    : " & err.Source))

        Dim numPar As Integer
        For Each numPar In err.NumericErrorParameters
            If 0 <> numPar Then
                bld.Append((ControlChars.Cr & " Num. Par. : " & numPar))
            End If
        Next numPar

        Dim errPar As String
        For Each errPar In err.ErrorParameters
            If [String].Empty <> errPar Then
                bld.Append((ControlChars.Cr & " Err. Par. : " & errPar))
            End If
        Next errPar

        MessageBox.Show(bld.ToString())
        bld.Remove(0, bld.Length)
    Next err

End Sub 'DisplaySqlCeErrors

public void DisplaySqlCeErrors(SqlCeErrorCollection errorCollection ) {
    StringBuilder bld = new StringBuilder();

    foreach (SqlCeError err in errorCollection) {
        bld.Append("\n Error Code: " + err.HResult.ToString("X"));
        bld.Append("\n Message   : " + err.Message);
        bld.Append("\n Minor Err.: " + err.NativeError);
        bld.Append("\n Source    : " + err.Source);
            
        foreach (int numPar in err.NumericErrorParameters) {
            if (0 != numPar) bld.Append("\n Num. Par. : " + numPar);
        }
            
        foreach (string errPar in err.ErrorParameters) {
            if (String.Empty != errPar) bld.Append("\n Err. Par. : " + errPar);
        }

        MessageBox.Show(bld.ToString());
        bld.Remove(0, bld.Length);
    }
}
