C# 在TransactionScope范围内打开新的数据库连接,而不在事务中登记
是否可以在TransactionScope内打开新的SqlConnection,而不引用事务中的其他连接?在事务内部,我需要运行另一个不应参与事务的命令C# 在TransactionScope范围内打开新的数据库连接,而不在事务中登记,c#,transactionscope,C#,Transactionscope,是否可以在TransactionScope内打开新的SqlConnection,而不引用事务中的其他连接?在事务内部,我需要运行另一个不应参与事务的命令 void test() { using (var t = new TransactionScope()) using (var c = new SqlConnection(constring)) { c.Open(); try { using (
void test() {
using (var t = new TransactionScope())
using (var c = new SqlConnection(constring))
{
c.Open();
try
{
using (var s = new SqlCommand("Update table SET column1 = 1");
{
s.ExecuteScalar(); // If this fails
}
t.Complete();
}
catch (Exception ex)
{
SaveErrorToDB(ex); // I don't want to run this in the same transaction
}
}
}
// I don't want this to get involved in the transaction, because it would generate
// a Distributed transaction, which I don't want. I Just want the error to go to the
// db not caring about it is run inside the TransactionScope of the previous function.
void SaveErrorToDB(Exception ex) {
using (var db = new SqlConnection(constring)) {
db.Open();
using (var cmd = new SqlCommand("INSERT INTO ErrorLog (msg) VALUES (" + ex.Message + "))
{
cmd.ExecuteNonQuery();
}
}
}
我自己终于找到了: 另一个SqlConnection必须用“Enlist=false”初始化,那么该连接将不会在同一事务中登记:
using (var db = new SqlConnection(constring + ";Enlist=false")) {
...
或者,您的
SaveErrorToDB
方法可以建立连接:
void test() {
using (var t = new TransactionScope())
using (var c = new SqlConnection(constring))
{
c.Open();
try
{
using (var s = new SqlCommand("Update table SET column1 = 1");
{
s.ExecuteScalar(); // If this fails
}
t.Complete();
}
catch (Exception ex)
{
SaveErrorToDB(ex, c); // I don't want to run this in the same transaction
}
}
}
void SaveErrorToDB(Exception ex, SqlConnection c) {
using (var cmd = new SqlCommand("INSERT INTO ErrorLog (msg) VALUES (" + ex.Message + ", c))
{
cmd.ExecuteNonQuery();
}
}
您还应该能够使用(var t=newtransactionscope(TransactionScopeOptions.Suppress)){}
