c# - MVC 方法不接收 json 数组作为列表

Question

我的 MVC 方法正在接收模型的其余部分，但不是我的列表

JavaScript:

var userSettings = [ { Name: "SettingName", Value: "SettingValue" }, { Name: "SettingName1", Value: "SettingValue2" }];

var data = {
    Email: "thing@what.com",
    Password: "123",
    ConfirmPassword: "123",
    UserSettings: JSON.stringify(userSettings)
}

$.ajax({
    url: this.action,
    type: "POST",
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify(data)

})

C#/MVC

[HttpPost]
public ActionResult Create(CreateUser model)
{
    //stuff
}

public class CreateUser
{
    public string Email { get; set; }
    public string Password { get; set; }
    public string ConfirmPassword { get; set; }
    public List<NameValue> UserSettings { get; set; }
}

public class NameValue
{
    public string Name { get; set; }
    public string Value { get; set; }
}

我在这里错过了什么？为什么我的 UserSettings 总是空着？

如果我将 UserSettings 更改为 String 而不是 List，它会收到 json 字符串，但我无法将其作为列表接收

Answer 1

不要将 userSettings 字符串化。

这样做会创建带有转义引号的字符串，而 MVC 将不知道如何绑定(bind)它。

使用字符串化:

"{"Email":"thing@what.com","Password":"123","ConfirmPassword":"123","UserSettings":"[{\"Name\":\"SettingName\",\"Value\":\"SettingValue\"},{\"Name\":\"SettingName1\",\"Value\":\"SettingValue2\"}]"}"

没有字符串化:

"{"Email":"thing@what.com","Password":"123","ConfirmPassword":"123","UserSettings":[{"Name":"SettingName","Value":"SettingValue"},{"Name":"SettingName1","Value":"SettingValue2"}]}"

您的代码应如下所示:

var data = {
    Email: "thing@what.com",
    Password: "123",
    ConfirmPassword: "123",
    UserSettings: userSettings
}
