發行項

收集由 .NET Compact Framework Data Provider for SQL Server Compact 3.5 所產生的所有錯誤。這個類別無法被繼承。

命名空間： System.Data.SqlServerCe
組件： System.Data.SqlServerCe (在 System.Data.SqlServerCe.dll 中)

語法

'宣告
Public NotInheritable Class SqlCeErrorCollection _
    Implements ICollection, IEnumerable
'用途
Dim instance As SqlCeErrorCollection

public sealed class SqlCeErrorCollection : ICollection, 
    IEnumerable

public ref class SqlCeErrorCollection sealed : ICollection, 
    IEnumerable

[<SealedAttribute>]
type SqlCeErrorCollection =  
    class
        interface ICollection
        interface IEnumerable
    end

public final class SqlCeErrorCollection implements ICollection, IEnumerable

備註

這個類別是由 SqlCeException 建立，可收集 SqlCeError 類別的執行個體。SqlCeErrorCollection 一定會至少包含一個 SqlCeError 類別的執行個體。

範例

下列範例會顯示 SqlCeErrorCollection 集合內的每個 SqlCeError。

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);
    }
}
