在我的MVC项目中，我在返回特定内容时遇到错误 System.InvalidOperationException：传递到字典中的模型项的类型为＆＃39; System.Collections.Generic.List`1 [AVASupplierPortal.Models.PurchaseOrder]＆＃39;，但此字典需要类型为＆＃的模型项39; AVASupplierPortal.Models.PurchaseOrder＆＃39;
如何显示要查看的列表数据？

在控制器中： 当你这样做
import threading
import time
def timeout():
for i in range(10):
time.sleep(0.1)
print('stop all bla loops now')
billy = 'timeout'
def loops():
for i in range(5):
time.sleep(0.1)
print('loop1')
billy = 'loop1 done'
for i in range(5):
time.sleep(0.1)
print('loop2')
billy = 'loop2 done'
for i in range(5):
time.sleep(0.1)
print('loop3')
billy = 'loop3 done'
billy = 'cool'
loops = threading.Thread(target=loops).start()
timeout = threading.Thread(target=timeout).start()
在视图中
View(*THIS IS YOUR MODEL*)
这两件事需要匹配，否则你会得到那个错误。像oppassum说的那样，阅读错误：
@model *THIS IS YOUR MODEL*
列表与单项。
