Question

使用DbContext我连接数据库并执行简单查询：

var results = dbContext.Database.SqlQuery<ResultDto>(MyQuery).ToList();

对我来说有点奇怪..我在上面一行之后得到了所有这些例外：

Exception thrown: 'System.Data.SqlClient.SqlException' in System.Data.dll
Exception thrown: 'System.Data.SqlClient.SqlException' in System.Data.dll
Exception thrown: 'System.Data.SqlClient.SqlException' in System.Data.dll

Exception thrown: 'System.Data.Entity.Core.EntityCommandExecutionException' in EntityFramework.SqlServer.dll

我的问题是：为什么我在Visual Studio输出窗口中获取它们...但我无法在try catch中捕获它们。这是我做的（没有成功）：

        try
        {
            var results = dbContext.Database.SqlQuery<ResultDto>(MyQuery).ToList();
        }
        catch (System.Data.SqlClient.SqlException sqlException)
        {

        }
        catch (Exception ex)
        {

        }

最重要的部分（我完全忘了）我收到了很好的数据..这条线基本上有效！但是将异常抛出到Output窗口......

输出中的SqlException但未被try-catch
