From a comment from the OP:

try 
{
  connection.Open();
  st = connection.BeginTransaction();
  commandToFinding = new SqlCommand(sqlqueryToFinding, connection,st);
  if (numToFinding != 0)
  {
    st.Commit();
    Response.Redirect("AddStudy.aspx?stid=" + StudyIDTextBox.Text);
    connection.Close();
  }
}
catch(Exception)
{
  st.Rollback(); // Exception happens here (This SqlTransaction has completed; it is no longer usable.)
  connection.Close();
}

推荐答案

我不同意您的意见. InvalidOperationException继承自Exception类.抛出的任何异常都将由您显示的代码块来处理.

I do not agree with you. InvalidOperationException is inherited from Exception class. Any excpetion thrown would be handled by the code block you have shown.

也许您正在捕获一个异常，然后在catch块中引发了另一个异常?毕竟，根据对其他答案的评论，您正在catch块中执行数据库操作(回滚并关闭连接).我没看过这些操作是否会引发您的特定异常，但是您应该检查一下.

Perhaps you''re catching an exception and then throwing another exception in your catch block? After all, according to your comments to other answers, you''re performing DB operations in your catch block (a rollback and closing a connection). I haven''t looked to see if either of those operations could throw your particular exception, but you should check.

您是否考虑过使用多个catch块?
您为什么不按以下步骤抓挡并尝试?

Did you consider Making use of Multiple catch blocks ??

Why dont you make you catch block as follows and try ?

catch ( InvalidOperationException e )
{
 // Perform task
}
catch ( Exception e )
{
 // Perform Task
}
finally
{
// Perform Talk
}
