public function set IsolationLevel (value : IsolationLevel)

属性值

Returns an integer value that corresponds to the isolation level.

备注

The default value of this property is -1, or Unspecified. For more information about isolation levels and their use by SQL Server, see 数据库引擎中的隔离级别. For more information about the available values, see the IsolationLevel enumerations used in the System.Data namespace in ADO and in OLE DB.

The following table lists the available values for the IsolationLevel property:

Value	Isolation Level
-1	Unspecified
16	Chaos
256	ReadUncommitted
4096	ReadCommitted
65536	RepeatableRead
1048576	Serializable

示例

The following code example creates a Package, which is a class that inherits from DtsContainer. The Package shows the use of several inherited properties.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace Microsoft.SqlServer.SSIS.Samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            Package pkg = new Package();

            // Package name must be assigned.
            pkg.Name = "My DtsContainer inheritance test package";

            // Display the values that manually assigned.
            Console.WriteLine("Package Name: {0}", pkg.Name);

            // Packages are assigned the following default values when created.
            Console.WriteLine("Package ID:           {0}", pkg.ID);
            Console.WriteLine("FailPackageOnFailure: {0}", pkg.FailPackageOnFailure);
            Console.WriteLine("FailParentOnFailure:  {0}", pkg.FailParentOnFailure);
            Console.WriteLine("Locale ID:            {0}", pkg.LocaleID);
            Console.WriteLine("Is DefaultLocaleID?   {0}", pkg.IsDefaultLocaleID);
            Console.WriteLine("Isolation Level:      {0}", pkg.IsolationLevel);
            Console.WriteLine("LoggingMode:          {0}", pkg.LoggingMode);
            Console.WriteLine("MaximumErrorCount:    {0}", pkg.MaximumErrorCount);
            Console.WriteLine("TransactionOption:    {0}", pkg.TransactionOption);
        }
    }
}

    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim app As Application =  New Application() 
            Dim pkg As Package =  New Package() 
 
            ' Package name must be assigned.
            pkg.Name = "My DtsContainer inheritance test package"
 
            ' Display the values that manually assigned.
            Console.WriteLine("Package Name: {0}", pkg.Name)
 
            ' Packages are assigned the following default values when created.
            Console.WriteLine("Package ID:           {0}", pkg.ID)
            Console.WriteLine("FailPackageOnFailure: {0}", pkg.FailPackageOnFailure)
            Console.WriteLine("FailParentOnFailure:  {0}", pkg.FailParentOnFailure)
            Console.WriteLine("Locale ID:            {0}", pkg.LocaleID)
            Console.WriteLine("Is DefaultLocaleID?   {0}", pkg.IsDefaultLocaleID)
            Console.WriteLine("Isolation Level:      {0}", pkg.IsolationLevel)
            Console.WriteLine("LoggingMode:          {0}", pkg.LoggingMode)
            Console.WriteLine("MaximumErrorCount:    {0}", pkg.MaximumErrorCount)
            Console.WriteLine("TransactionOption:    {0}", pkg.TransactionOption)
        End Sub
    End Class
End Namespace
