SqlErrorCollection 類別

定義

public ref class SqlErrorCollection sealed : System::Collections::ICollection

[System.ComponentModel.ListBindable(false)]
[System.Serializable]
public sealed class SqlErrorCollection : System.Collections.ICollection

[<System.ComponentModel.ListBindable(false)>]
[<System.Serializable>]
type SqlErrorCollection = class
    interface ICollection
    interface IEnumerable

Public NotInheritable Class SqlErrorCollection
Implements ICollection

繼承

Object

SqlErrorCollection

屬性

ListBindableAttribute SerializableAttribute

實作

ICollection IEnumerable

範例

以下範例顯示每個集合中的SqlError每個角色SqlErrorCollection。

public static void ShowSqlException(string connectionString)
{
    string queryString = "EXECUTE NonExistantStoredProcedure";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(queryString, connection);
        try
        {
            command.Connection.Open();
            command.ExecuteNonQuery();
        }
        catch (SqlException ex)
        {
            DisplaySqlErrors(ex);
        }
    }
}

private static void DisplaySqlErrors(SqlException exception)
{
    for (int i = 0; i < exception.Errors.Count; i++)
    {
        Console.WriteLine("Index #" + i + "\n" +
            "Error: " + exception.Errors[i].ToString() + "\n");
    }
    Console.ReadLine();
}

Public Sub ShowSqlException(ByVal connectionString As String)
    Dim queryString As String = "EXECUTE NonExistantStoredProcedure"

    Using connection As New SqlConnection(connectionString)
        Dim command As New SqlCommand(queryString, connection)

        Try
            command.Connection.Open()
            command.ExecuteNonQuery()

        Catch ex As SqlException
            DisplaySqlErrors(ex)
        End Try
    End Using
End Sub

Private Sub DisplaySqlErrors(ByVal exception As SqlException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        Console.WriteLine("Index #" & i & ControlChars.NewLine & _
            "Error: " & exception.Errors(i).ToString() & ControlChars.NewLine)
    Next i
    Console.ReadLine()
End Sub

備註

此類別的建立 SqlException 用以收集該 SqlError 類別的實例。 SqlErrorCollection 總是至少包含一個該 SqlError 類別的實例。
