System.Transactions.TransactionException
System.Transactions.TransactionException
我有以下代码：
[TestMethod]
public void CalculateThatWeHaveAllRetrunFromProxyImmo()
{
var test = new BaseDataAccess();
var sessionDateParam = new SqlParameter("@SessionDate", new DateTime(1900, 01, 31));
var dateDebutParam = new SqlParameter("@DateDebutHistoricRendement", new DateTime(1999, 01, 31));
var datefinParam = new SqlParameter("@DateFinHistoricRendement", new DateTime(2015, 01, 31));
var idProxyParam = new SqlParameter("@IdRealEstateProxy", 15);
var blocElementParam = new SqlParameter("@BlocNbrElement", 1501);
for (int index = 0; index < 17; index++)
{
Debug.WriteLine("Passage : " + index);
var ds = new DataSet();
SqlConnection conn = null;
using (conn = test.CreateAndOpenConnection())
{
SqlCommand cmd = null;
using (cmd = new SqlCommand("[Core].[cp_CalculAllReturnProxyImmo]", conn))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandTimeout = 1000000;
cmd.Parameters.Add(sessionDateParam);
cmd.Parameters.Add(dateDebutParam);
cmd.Parameters.Add(datefinParam);
cmd.Parameters.Add(idProxyParam);
cmd.Parameters.Add(blocElementParam);
using (SqlDataAdapter adapter = new SqlDataAdapter(cmd))
{
adapter.Fill(ds);
}
cmd.Parameters.Clear();
}
}
}
和
/// <summary>
/// Creates our connection to the database.
/// </summary>
/// <returns>The SqlConnection object.</returns>
public SqlConnection CreateAndOpenConnection()
{
SqlConnection connection = null;
try
{
connection = new SqlConnection(Settings.Default.DbConnection);
connection.Open(); // the error appears here after 14 iterations
}
catch (SqlException sqlException)
{
}
catch (Exception exception)
{
}
return connection;
}
这是连接
connectionString="Data Source=xxx\yyy;Initial Catalog=BD;Integrated Security=True;Max Pool Size=5000"
每次我在循环中到达索引 14 时，我都会得到一个 System.Transactions.TransactionException。
但是我的代码中没有打开任何事务。没看懂。
这是完整的堆栈：

根据要求，您将 Assert.IsTrue(Transaction.Current == null); 添加到测试中。断言被解雇了。这证明有一个 System.Transactions.Transaction 集是你不知道的。这就解释了症状。您无意中使用了分布式事务（如果您不使用它们，最好禁用 MSDTC 服务，这样它们会立即失败，而不是偶尔失败！）。
无法确定该交易的位置。 Grep "Transaction" 的整个源代码。添加更多断言。
可能是另一个测试设置了该事务并泄露了它。交叉测试交互很难调试。通过逐渐减少您 运行 直到问题消失的测试集来缩小范围。
