一个查询：

<div id="ft" style="padding:2px 5px;">
    学号:<input id="Id" name="Id" class="textbox" type="text" />
    <a href="#" class="easyui-linkbutton" iconCls="icon-search" plain="true" onclick="obj.search()"></a>
    姓名:<input id="Name" name="Name" class="textbox" type="text" />
    <a href="#" class="easyui-linkbutton" iconCls="icon-search" plain="true" onclick="obj.search()"></a><br />
    性别:<input id="Sex" name="Sex" class="textbox" type="text" />
    <a href="#" class="easyui-linkbutton" iconCls="icon-search" plain="true" onclick="obj.search()"></a>
    年龄:<input id="Age" name="Age" class="textbox" type="text" />
    <a href="#" class="easyui-linkbutton" iconCls="icon-search" plain="true" onclick="obj.search()"></a>
</div>

var obj = {
    search: function () {

        $(‘#studentInfo‘).datagrid(‘load‘, {
            id: $(‘#Id‘).val().trim(),
            name: $(‘#Name‘).val().trim(),
            sex: $(‘#Sex‘).val().trim(),
            age: $(‘#Age‘).val().trim()
        });

    }
};

控制器：

public JsonResult getJson(int page, int rows, string age, string sex, string name, string id)
        {
            var st=db.student.Where(s=>s.id.Contains(id)&&s.name.Contains(name)&&s.sex.Contains(sex)&&SqlFunctions.StringConvert((double)s.age).Contains(age)).ToList();
            return Json(new { total = st.Count, rows = st.Skip((page - 1) * rows).Take(rows) });
        }
