action:

[HttpGet]
public IActionResult ConfigEdit(int id)
{
ConfigModel model = configBLL.GetModel(id);
return View(model);
}

View的内容也很简单，都是框架自动生成的：

@model Model.ConfigModel
@{
ViewData["Title"] = "编辑配置";
Layout = "~/Areas/manager/Views/Shared/_Layout.cshtml";
}
<h2>编辑配置</h2>
<hr />
<div class="row">
<div class="col-md-4">
<form asp-action="ConfigEdit">
<div asp-validation-summary="ModelOnly " class="text-danger"></div>
<div class="form-group">
<label asp-for="id" class="control-label"></label>
<input asp-for="id" class="form-control" />
<span asp-validation-for="id" class="text-danger"></span>
</div>
<div class="form-group hidden">
<label asp-for="type" class="control-label"></label>
<input asp-for="type" class="form-control" />
<span asp-validation-for="type" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="title" class="control-label"></label>
<input asp-for="title" class="form-control" />
<span asp-validation-for="title" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="description" class="control-label"></label>
<textarea asp-for="description" rows="5" class="form-control"></textarea>
<span asp-validation-for="description" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="name" class="control-label"></label>
<input asp-for="name" class="form-control" />
<span asp-validation-for="name" class="text-danger"></span>
</div>
<div class="form-group hidden">
<label asp-for="valuetype" class="control-label"></label>
<input asp-for="valuetype" class="form-control" />
<span asp-validation-for="valuetype" class="text-danger"></span>
</div>

<div class="form-group">

<input type="submit" value="Save" class="btn btn-default" />
</div>
</form>
</div>
</div>

约定id的参数是需要int类型。

当id传入数字时，正常，能正确获取数据。

但当id传入非数字时，报错，

生成的内容是这样：

<div class="form-group">
                <label class="control-label" for="id">id</label>
                <input class="form-control input-validation-error" type="number" data-val="true" data-val-required="The id field is required." id="id" name="id" value="sfsf" />
                <span class="text-danger field-validation-error" data-valmsg-for="id" data-valmsg-replace="true">The value &#x27;sfsf&#x27; is not valid.</span>
            </div>

模型：

        /// <summary>
        /// id
        /// </summary>
        [Key]
        [Display(Name ="id")]
        public int id { get; set; }

错误提示：The value 'sfsf' is not valid. 这句在哪里修改？在模型中试了都不对啊。
