C# 对于大型嵌套复选框列表，ASP.NET MVC表单发布速度非常慢

我的ASP.NET MVC web应用程序有问题，在发布表单时，我的

ViewModel

需要约30秒才能击中我的控制器。我猜这与默认的模型绑定器有关，因为这样

[HttpPost]
public ActionResult Edit(ByActivityEditViewModel viewModel)
{
    if (ModelState.IsValid) // Takes ~30 seconds before even hitting this
    {

我的

视图

是

组

父项和

用户

子项的一系列嵌套复选框。相同的

用户

可以列在多个

组下

。我正在使用

EditorFor

为

ViewModel

生成复选框

视图的编辑器模板调用：

@Html.EditorFor（model=>model.Groups）

编辑器模板：

@model MyProject.Models.Group
@Html.HiddenFor(model => model.Guid)
@Html.HiddenFor(model => model.Name)
@Html.CheckBoxFor(model => model.IsAllowed, new { @class = Model.Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => model.IsAllowed, Model.Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })

@if (Model.Users.Any())
{
    <ul style="list-style:none;">
        @for (int i = 0; i < Model.Users.Count; i++)
        {

ModelState:

@Html.HiddenFor(model => model.Guid)
@Html.HiddenFor(model => model.Name)
@Html.CheckBoxFor(model => model.IsAllowed, new { @class = Model.Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => model.IsAllowed, Model.Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })

@if (Model.Users.Any())
{
    <ul style="list-style:none;">
        @for (int i = 0; i < Model.Users.Count; i++)
        {
            <li>
                @Html.HiddenFor(model => Model.Users[i].Guid)
                @Html.HiddenFor(model => Model.Users[i].Name)
                @Html.CheckBoxFor(model => Model.Users[i].IsAllowed, new { @class = Model.Users[i].Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => Model.Users[i].IsAllowed, Model.Users[i].Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })
            </li>
        }
    </ul>
}

public class ByActivityEditViewModel
{
    public int ActivityId { get; set; }
    public string Path { get; set; }
    public IList<Group> Groups { get; set; } = new List<Group>();
}

public class Group
{
    public Guid? Guid { get; set; }
    public string Name { get; set; }
    public string DistinguishedName { get; set; }
    public string SamAccountName { get; set; }
    public string DisplayName { get; set; }
    public bool IsAllowed { get; set; }
    public List<User> Users { get; set; } = new List<User>();
}

public class User
{
    public Guid? Guid { get; set; }
    public string Name { get; set; }
    public string DistinguishedName { get; set; }
    public string SamAccountName { get; set; }
    public string DisplayName { get; set; }
    public bool IsAllowed { get; set; }
    public bool IsUserChecked { get; set; }
}

模型状态包含GUID、名称和IsAllowed值。我认为这是缓慢的部分

结果是：

@model MyProject.Models.Group
@Html.HiddenFor(model => model.Guid)
@Html.HiddenFor(model => model.Name)
@Html.CheckBoxFor(model => model.IsAllowed, new { @class = Model.Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => model.IsAllowed, Model.Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })

@if (Model.Users.Any())
{
    <ul style="list-style:none;">
        @for (int i = 0; i < Model.Users.Count; i++)
        {
            <li>
                @Html.HiddenFor(model => Model.Users[i].Guid)
                @Html.HiddenFor(model => Model.Users[i].Name)
                @Html.CheckBoxFor(model => Model.Users[i].IsAllowed, new { @class = Model.Users[i].Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => Model.Users[i].IsAllowed, Model.Users[i].Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })
            </li>
        }
    </ul>
}

public class ByActivityEditViewModel
{
    public int ActivityId { get; set; }
    public string Path { get; set; }
    public IList<Group> Groups { get; set; } = new List<Group>();
}

public class Group
{
    public Guid? Guid { get; set; }
    public string Name { get; set; }
    public string DistinguishedName { get; set; }
    public string SamAccountName { get; set; }
    public string DisplayName { get; set; }
    public bool IsAllowed { get; set; }
    public List<User> Users { get; set; } = new List<User>();
}

public class User
{
    public Guid? Guid { get; set; }

• 64组
• 853个用户

用户可以是多个组的一部分

我试过了：

@model MyProject.Models.Group
@Html.HiddenFor(model => model.Guid)
@Html.HiddenFor(model => model.Name)
@Html.CheckBoxFor(model => model.IsAllowed, new { @class = Model.Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => model.IsAllowed, Model.Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })

@if (Model.Users.Any())
{
    <ul style="list-style:none;">
        @for (int i = 0; i < Model.Users.Count; i++)
        {
            <li>
                @Html.HiddenFor(model => Model.Users[i].Guid)
                @Html.HiddenFor(model => Model.Users[i].Name)
                @Html.CheckBoxFor(model => Model.Users[i].IsAllowed, new { @class = Model.Users[i].Guid.ToString(), @style = "margin-right:5px; cursor:pointer;" }) @Html.LabelFor(model => Model.Users[i].IsAllowed, Model.Users[i].Name, new { @class = "build-checkbox-label", @style = "font-weight:normal; margin-top:-2px;" })
            </li>
        }
    </ul>
}

public class ByActivityEditViewModel
{
    public int ActivityId { get; set; }
    public string Path { get; set; }
    public IList<Group> Groups { get; set; } = new List<Group>();
}

public class Group
{
    public Guid? Guid { get; set; }
    public string Name { get; set; }
    public string DistinguishedName { get; set; }
    public string SamAccountName { get; set; }
    public string DisplayName { get; set; }
    public bool IsAllowed { get; set; }
    public List<User> Users { get; set; } = new List<User>();
}

public class User
{
    public Guid? Guid { get; set; }
    public string Name { get; set; }
    public string DistinguishedName { get; set; }
    public string SamAccountName { get; set; }
    public string DisplayName { get; set; }
    public bool IsAllowed { get; set; }
    public bool IsUserChecked { get; set; }
}

使用字符串作为Guid，并在以后对其进行分析

任何建议、信息或解决方法都将不胜感激。

因此，除非您阅读评论，否则从帖子中不清楚修复方法是什么。因此，答案是在@using（Html.BeginForm（））之前添加@Html{Html.EnableClientValidation（false）；}

---

这将关闭默认的客户端验证，并使您更快地向服务器发送表单。当然，如果您需要客户端验证，那么这不是解决方案。在我的例子中，我的表单有200行带有复选框，我不需要客户端验证。所以这个解决方案对我来说非常有效。

您是否使用任何js/JQUR库来装饰或验证？例如，你应该试试Chrome开发者/调试工具，看看会发生什么。尽管如此，浏览器需要处理很多复选框。@Niko这是jquery验证，我不需要复选框。非常感谢。我在模型活页夹上完全有隧道式的视觉。如果你把这个作为答案，我很乐意给你赏金。我相信它将来会帮助别人。我使用

@{Html.EnableClientValidation（false）；}

在视图中关闭它。
