这段代码中的错误是什么？它无法在数据库中保存数据 [英] What's the error in this code? Its not working not able to save data in the database

问题描述

protected void btnSubmit_Click(object sender, EventArgs e)
    {
        ProductModel productModel = new ProductModel();
        Product product = CreateProduct();

        lblResult.Text = productModel.InsertProduct(product);



    }

我的尝试：

What I have tried:

protected void btnSubmit_Click(object sender, EventArgs e)
    {
        ProductModel productModel = new ProductModel();
        Product product = CreateProduct();

        lblResult.Text = productModel.InsertProduct(product);



    }

推荐答案

我只能看到（或建议）一个这里的事情，

I can only see (or suggest) one thing here,

lblResult.Text = productModel.InsertProduct(product);

InsertProduct 函数必须返回字符串值，因为 Text 属性 Label 对象有一个String类型，所以要么这样做，要么在结果上调用ToString函数，比如，

The InsertProduct function must return a string value, because the Text property of Label objects has a type of String, so either do that, or call a ToString function on the result, like,

lblResult.Text = productModel.InsertProduct(product).ToString();

其次，从你捕获该代码的任何地方，你需要问他们为什么写这个代码办法。此外，您可以将代码更改为以下代码，这将是一种更好的方法，

Secondly, from wherever you captured that code, you need to ask them why they wrote it this way. Also, you can change the code to the following one and would be a better approach,

productModel.InsertProduct(product);
lblResult.Text = "Product added."

很简单，也有更好的用户体验！

Much simple, and a better UX as well!
