EntietyFramework无法捕获DbUpdateException

Question

当从MySQL数据库中删除与其他表相关的对象时，捕获DbUpdateException时出现问题，并且DbContext.SaveChanges（）会引发该确切异常。

以下代码未捕获异常：

    public async Task<ActionResult<JobTitle>> DeleteJobtitle(int id) {
        var jobtitle = await _context.Jobtitle.FindAsync(id);

        if (jobtitle == null) {
            return NotFound();
        }

        _context.Jobtitle.Remove(jobtitle);

        try {
            _context.SaveChanges();
        }
        catch (DbUpdateException ex) {
            Console.WriteLine("exception: " + ex.Message);
        }

        return jobtitle;
    }

这是发生异常时的控制台输出：

 Microsoft.EntityFrameworkCore.Database.Command[20102]
  Failed executing DbCommand (1,601ms) [Parameters=[@p0='?' (DbType = Int32)], CommandType='Text', CommandTimeout='30']
  DELETE FROM `jobtitle`
  WHERE `idJobTitle` = @p0;
  SELECT ROW_COUNT();
fail: Microsoft.EntityFrameworkCore.Update[10000]
  An exception occurred in the database while saving changes for context type 'DbAPI.DbContexts.DbContext'.
  Microsoft.EntityFrameworkCore.DbUpdateException: An error occurred while updating the entries. See the inner exception for details.

为什么我的try catch块无法捕获异常？
