在前端页面中，如果没有表单，想把复杂对象提交到后端，可使用以下方法
后端Controller中定义以下方法：
[HttpPost] ???????public int AddSolution([FromBody]Solution col) ???????{ ???????????if (col != null) ???????????{ ???????????????//你的操作 ???????????} ???????????else ???????????{ ???????????????return -1; ???????????} ???????????return 1; ???????}注意一定要有 [FromBody]
前端JS方法
function fn_addSolution() { ????????var data = { ???????????????TableName: "UserTable", ???????????????Name:"lisi", ???????????????DisplayName: "李斯", ???????}; ???????????????$.ajax({ ???????????type: "POST", ???????????url: "/Solution/AddSolution", ???????????data: JSON.stringify(data), ???????????contentType: "application/json; charset=utf-8", ???????????dataType: "json", ???????????success: function (result) { ???????????????if (result) ???????????} ???????}); ???}注意其中的 contentType和dataType
