我正在我的项目中编写一个网站我使用了身份，因为您知道身份使用“GUID”类型为“id”，但是当我想在“模态弹出窗口”中获取用户信息时我有一个问题我需要将“int”值与“GUID”进行比较但我不能这样做。例如：
if（Model！= null＆amp;＆amp; Model.Id＆gt; 0）//我收到了错误（ 运营商'＆gt;'不能应用于'string'类型的操作数 ）
@model DataLayer.User
@using (Html.BeginForm("Edit", "users", FormMethod.Post, new { id = "popupForm" }))
{
if (Model != null && Model.Id > 0)
{
@Html.HiddenFor(a => a.Id)
}
<div class="form-group">
<label>User Name</label>
@Html.TextBoxFor(a => a.UserName, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.UserName)
</div>
<div class="form-group">
<label>First Name</label>
@Html.TextBoxFor(a => a.FirstName, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.FirstName)
</div>
<div class="form-group">
<label>Last Name</label>
@Html.TextBoxFor(a => a.LastName, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.LastName)
</div>
<div class="form-group">
<label>Gender</label>
@Html.TextBoxFor(a => a.Gender, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.Gender)
</div>
<div class="form-group">
<label>Condition</label>
@Html.TextBoxFor(a => a.IsActive, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.IsActive)
</div>
<div class="form-group">
<label>Email</label>
@Html.TextBoxFor(a => a.Email, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.Email)
</div>
<div class="form-group">
<label>Address</label>
@Html.TextBoxFor(a => a.Address, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.Address)
</div>
<div class="form-group">
<label>PhoneNumber</label>
@Html.TextBoxFor(a => a.PhoneNumber, new { @class = "form-control" })
@Html.ValidationMessageFor(a => a.PhoneNumber)
</div>
<div>
<input type="submit" value="Edite" />

答案 0 :(得分：0)
而不是
Model.Id > 0
使用它 - 因为它是Guid Type列。
Model.Id != Guid.Empty
