我有一个C#worker类(不是ASPX页面的一部分),可以进行一些SQL连接。该类本身是静态的,并由ASMX Web服务实例化。
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AjaxServices : System.Web.Services.WebService
{
/// <summary>
/// This calls the worker class for the long-running process.
/// </summary>
static RunCreatorClient workProcessor = new RunCreatorClient();
[WebMethod]
[ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
public String StartProcess(DateTime date, string name) //starts the process
在worker类中,我有连接到SQL Server并执行命令的代码。问题是,我无法使SYSTEM_USER等于登录用户。它总是连接到SQL作为执行机器名。
using System.Security.Principal;
using (WindowsIdentity.GetCurrent().Impersonate())
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString()))
{
此方法StartProcessing()
启动SQL作业。
/// <summary>
/// Worker class that executes a long-running process.
/// </summary>
public class RunCreatorClient
{
/// <summary>
/// Non-blocking call that starts running the long-running process.
/// </summary>
public void StartProcessing()
{
// Reset the properties that report status.
IsComplete = false;
IsRunning = true;
PercentComplete = 0;
// Kick off the actual, private long-running process in a new Task
task = Task.Factory.StartNew(() =>
{
CommitToDb();
});
}
答案 0 :(得分:1)
您需要将CommitToDb()
括在模拟的上下文中。
using System.Security.Principal;
WindowsIdentity impersonatedUser = WindowsIdentity.GetCurrent();
// Kick off the actual, private long-running process in a new Task
task = Task.Factory.StartNew(() =>
{
using(WindowsImpersonationContext ctx = impersonatedUser.Impersonate())
{
CommitToDb();
}
});
