C# MVC-ActionLink-参数字典包含参数'；id'；不可为空的类型

我在将视图中的ID与控制器匹配时遇到问题

当用户选择edit时，它将指向一个编辑页面，所选行的ID将传递给控制器，但是它会出现错误，即“参数字典包含非null类型的参数'ID'的null条目”，即使我尝试硬编码“ID=#”，它仍然计为null

我的看法是：

@model Mvc4_Development_Test.Models.Customer.CustomerDTO
@using Mvc4_Development_Test.Models.Customer

@{
    ViewBag.Title = "Customers Index";
    Mvc4_Development_Test.Models.Customer.CustomerListBO tblHeader = Model.CustomerList.FirstOrDefault( );
}

<h2 style="text-align:center">Customers Index</h2>

<br />

@using ( Html.BeginForm( "ViewCustomer" , "Customer" , FormMethod.Get , new { id = "fm_SearchFilter" } ) )

{
    <fieldset style="margin-left: 110px;">
        <div class="editor-label">
            @Html.LabelFor( model => model.searchFunction.Customer_Name )
        </div>
        <div class="editor-field">
            @Html.EditorFor( model => model.searchFunction.Customer_Name )


            @Html.DropDownListFor( model => model.searchFunction.Stat_ID , new SelectList( Model.StatList , "Stat_ID" , "Stat_Desc" , Model.searchFunction.Stat_ID ) )

            <input type="submit" value="Search" style="margin-left: 10px;" />
            <a href="./CreateCustomer"><input type="button" value="Create Customer" /></a>
        </div>
    </fieldset>
}

我的模型

public int Customer_ID { get; set; }

public string Customer_Name { get; set; }

public string Customer_School { get; set; }

我不能将其作为可空字段，因为它是数据库上的ID

非常感谢您的帮助。

我通过在valueObject旁边添加一个null找到了答案，即：

<button>
@Html.ActionLink( "Edit" , "EditCustomer" , "Customer" , new { id = member.Customer_ID }, null )
</button>

@ActionLink（“编辑”、“编辑客户”、“客户”，新的{id=member.Customer\u id}，空）

生成的地址看起来正常吗？对不起，你的意思是什么？呈现的ActionLink的地址。呈现的ActionLink转到EditCustomer、Customer（Controller），我希望它使用Customer\u ID作为ID变量setRight，但发布呈现的链接。

<button>
@Html.ActionLink( "Edit" , "EditCustomer" , "Customer" , new { id = member.Customer_ID }, null )
</button>
