我可以强制ClassCleanup与ClassInitialize在同一线程中执行吗？

Question

In the code snippet below I'm using ClassInitialize and Cleanup to wrap transactions around a series of tests I'm running. The code works in my GUI test runner but fails in mstest command line with the below error. Am I able to force Class cleanup and initialize to be in same thread? Prefer not to use Test initialize and cleanup as it will slow the test significantly.

CODE

        private static TransactionScope _trans;

    [ClassInitialize]
    public static void ClassInitialize(TestContext context)
    {
        _trans = new TransactionScope();
        //...do work
    }

    [ClassCleanup]
    public static void ClassCleanup()
    {
        _trans.Dispose();
    }

ERROR

Run has the following issue(s): Class Cleanup method GeoMetExplainSheetTests.TestCleanup failed. Error Message: System.InvalidOperationException: A TransactionScope must be disposed on the same thread that it was created..

Stack Trace:

at System.Transactions.TransactionScope.Dispose()

我建议您通过删除static modifier来替换

private TransactionScope _trans;
