+MVC新增功能实现：
+关键：必须做前后端双重数据校验，确保数据合法性，新增后需给用户明确的结果反馈。
+```C#
+public async Task<IActionResult> Create([Bind("Id,Name,Age")] Student student)|
+{
+if (ModelState.IsValid) // 断点1：检查模型验证是否通过|
+{
+_context.Add(student); // 断点2：检查要新增的student数据|
+await _context.SaveChangesAsync(); // 断点3：执行数据库保存|
+return RedirectToAction(nameof(Index));
+}
+return View(student);
+}
+```
+MVC删除功能实现：
+关键：优先增加确认环节防误删，推荐使用 “软删除”，删除操作必须基于唯一主键，同时处理关联数据的异常情况。
+```C#
+public async Task<IActionResult> Delete(int? id) 
+{
+if (id == null \_context.Student == null)
+{
+return NotFound();
+}
+var student = await _context.Student.FirstOrDefaultAsync(m => m.Id == id); 
+if (student == null)
+{
+return NotFound();
+}
+return View(student);
+}
+```
