在接下来的步骤中,我需要将
nextDB
传递到 Retry 中的 Lambda 表达式中:Retry.Do(() =>
{
string nextDB = dbList.Next();
using (DataBaseProxy repo = new DataBaseProxy(nextDB))
{
return repo.DoSomething();
}
});
我该怎么做呢?这是我的Retry
类:
public static class Retry
{
public static void Do(
Action action,
int retryCount = 3)
{
Do<object>(() =>
{
action();
return null;
}, retryCount);
}
public static T Do<T>(
Func<T> action,
int retryCount = 3)
{
var exceptions = new List<Exception>();
for (int retry = 0; retry < retryCount; retry++)
{
try
{
return action();
}
catch (Exception ex)
{
exceptions.Add(ex);
}
}
throw new AggregateException(exceptions);
}
}
