c# - 创建新的地震采集海洋框架

Question

我正在尝试使用以下代码片段创建一个新的空地震集合。

Collection 已创建并添加到输入 Pane ，但尝试创建 NewSeismicCollection 会抛出一个

A plug-in has triggered error: Slb.Ocean.Core.TransactionLockException; Transaction lock failure.

if(seismicProj.SeismicCollectionCount == 0)
{
    PetrelLogger.InfoOutputWindow("No seismic collections in current project");
    using (ITransaction trans2 = DataManager.NewTransaction())
    {
        trans2.Lock(proj);
        Collection col2 = proj.CreateCollection("Collection"); 
    }

    using (ITransaction txn = DataManager.NewTransaction())
    {
        try
        {
            txn.Lock(seismicProj);
            SeismicCollection seisColl = seismicProj.CreateSeismicCollection(
                "NewSeismicCollection");
        }
        catch (InvalidOperationException e)
        {
            PetrelLogger.InfoOutputWindow(e.Message);
        }
        finally
        {
            txn.Commit();
        }
    }
}
else
{
    // do something else
}

不应该在您在 try block 中提交的单个事务中，如:

using (ITransaction txn = DataManager.NewTransaction())
{
    try
    {
        txn.Lock(proj);
        Collection col2 = proj.CreateCollection("Collection"); 
        txn.Lock(seismicProj);
        SeismicCollection seisColl = seismicProj.CreateSeismicCollection("NewSeismicCollection");
        txn.Commit();
    }
    catch (Exception e)
    {
        PetrelLogger.InfoOutputWindow(e.Message);
        throw;
    }
}

或者找出错误:尝试作为两个单独的事务:

using (ITransaction txn = DataManager.NewTransaction())
{
    try
    {
        txn.Lock(proj);
        Collection col2 = proj.CreateCollection("Collection"); 
        txn.Commit();
    }
    catch (Exception e)
    {
        PetrelLogger.InfoOutputWindow(e.Message);
        throw;
    }
}

using (ITransaction txn = DataManager.NewTransaction())
{
    try
    {
        txn.Lock(seismicProj);
        SeismicCollection seisColl = seismicProj.CreateSeismicCollection("NewSeismicCollection");
        txn.Commit();
    }
    catch (Exception e)
    {
        PetrelLogger.InfoOutputWindow(e.Message);
        throw;
    }
}
