研究了两三个小时，解决了C#保存图片物理路径，并显示在bootstrap上的问题，终于解决了
前端代码如下：

@using System.Web.Optimization
@using WarehouseManage.Model.Dto
@model Base_GoodsDto
@{

var goodsTypelist = new List<SelectListItem>
{
new SelectListItem
{
Selected = true,
Text = "请选择",
Value = String.Empty
}
};
var usingTypeList = new List<SelectListItem>
{
new SelectListItem
{
Selected = true,
Text = "请选择",
Value = String.Empty
}
};
var unitTypeList = new List<SelectListItem>
{
new SelectListItem
{
Selected = true,
Text = "请选择",
Value = String.Empty
}
};
var list = ViewBag.goodsTypeList as List<Base_GoodsTypeDto>;
if (list?.Any() == true)
{
foreach (var item in list)
{
goodsTypelist.Add(
new SelectListItem
{
Text = item.Name,
Value = item.TypeID.ToString()
});
}
}
var list2 = ViewBag.usingTypeList as List<Base_UsingTypeDto>;
if (list2?.Any() == true)
{
foreach (var item in list2)
{

Value = item.UsingTypeID.ToString()
});
}
}
var list3 = ViewBag.unitTypeList as List<Base_UnitDto>;
if (list3?.Any() == true)
{
foreach (var item in list3)
{
unitTypeList.Add(
new SelectListItem
{
Text = item.Name,
Value = item.UnitID.ToString()
});
}
}
}

注意：有几个坑
第一个坑：form表单提交的话加上enctype="multipart/form-data"
第二个坑：虽然我是用到了form但是在验证时，又使用了ajax提交，所以获取数据方式需要改变一下
jucheap.buttonLoading = function (form) {
$(form).find("button[type='submit']:first").queue(function () {
//form.submit();
var form = $("#submitForm")[0];
// Create an FormData object
var data = new FormData(form);
//var data = $(form).serializeArray()
var url = $(form).attr("action");;
$.ajax({
url: url,
enctype: 'multipart/form-data',
type: 'post',
data: data,
processData: false, //Important, it prevent jQuery form transforming the data into a query string
contentType: false,
cache: false,
dataType: 'json',
//contentType: 'application/x-www-form-urlencoded',
success: function (res) {
if (res.flag) {
layer.msg("保存成功", { icon: 1, time: 1000 });
setTimeout(function () {
yui.layer_close3();
}, 500);
window.parent.$('#table_server').bootstrapTable('refresh');
} else {
parent.layer.alert("保存失败:" + res.msg);
}
},
error: function (e) {
console.log(e);
}
});
$(form).find("button[type='submit']:first").dequeue();
});
}
controller层部分代码
HttpPostedFileBase postImage = Request.Files["ImagePath"];
string filePath = postImage.FileName;
string fileName = filePath.Substring(filePath.LastIndexOf("\\") + 1);
string serverPath = Server.MapPath(@"\Images\Goods\") + fileName;
string relativePath = @"/Images/Goods/" + fileName;
postImage.SaveAs(serverPath);
model.ImagePath = relativePath;
model.UserID = HttpContext.User.Identity.Name;
var goodsType = goodsTypeService.Get(x => x.TypeID == model.TypeID);
model.GoodsName = goodsType.Name + "-" + model.SpecsName;
goodsService.Update(model);
return Json(new { flag = true });
以代码参考了很多网上的方法，不同的人可能遇到的情况不同，希望静下心来慢慢解决
