C# 为控制器的检查输入创建自定义模型绑定
我已经使用.NET5创建了一个web应用程序，我想当用户在自定义模型绑定中创建帖子时，我检查输入价格是否超过7个数字，并且YearOfconstruction是否小于1401 post create，但如果有错误，请在前端显示，然后等待，直到用户输入最佳输入 以及编辑 如果可能，使用模型绑定存储imagename 我阅读了Microsoft文档中的自定义模型绑定，但不知道该怎么做 谢谢你的帮助 我很抱歉把代码完全留下了 房地产系统.Data.ApplicationDbContext.cs：C# 为控制器的检查输入创建自定义模型绑定,c#,asp.net-mvc,asp.net-core,C#,Asp.net Mvc,Asp.net Core,我已经使用.NET5创建了一个web应用程序，我想当用户在自定义模型绑定中创建帖子时，我检查输入价格是否超过7个数字，并且YearOfconstruction是否小于1401 post create，但如果有错误，请在前端显示，然后等待，直到用户输入最佳输入 以及编辑 如果可能，使用模型绑定存储imagename 我阅读了Microsoft文档中的自定义模型绑定，但不知道该怎么做 谢谢你的帮助 我很抱歉把代码完全留下了 房地产系统.Data.ApplicationDbContext.cs： us
