1. 方法一：利用ajax

　　1) 客户端js代码：

//获取对象数组
function GetQAS() {
    var stuAnswerList = [];
    var stuAnswer = { 'answerID': 1, 'answerType': 1, 'answerContent': 'one', 'answerSingle': 1, 'answerMultiple': '1,2', 'answerTOF': true };
    var stuAnswer1 = { 'answerID': 1, 'answerType': 1, 'answerContent': 'two', 'answerSingle': 1, 'answerMultiple': '1,2', 'answerTOF': true };

    stuAnswerList.push(stuAnswer);
    stuAnswerList.push(stuAnswer);
　　　　return stuAnswerList;
}
//ajax提交数据
function SubmitStuAnswersAjax(stuAnswerArr) {

    $.ajax({
        url: "../../Paper/SubmitStuAnswers",
        type: "post",
        data: { stuAnswerArr: stuAnswerArr },
        async: false,
        cache: false,
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            if (XMLHttpRequest.status == 1001) {
                eval(XMLHttpRequest.ResponseText);
            } else {
                alert("GetPaper error");
            }
        },
        success: function (data) {
            alert(data);
        }
    });
}
//按钮点击方法
function SubmitStuAnswersBtn() {
    var stuAnswerArr = GetQAS();
    SubmitStuAnswersAjax(stuAnswerArr);
}

　　2) 服务端C#代码：

//stuAnswerEntity
public class stuAnswerEntity
        {
            public int answerID { set; get; }
            public int answerType { set; get; }
            public int answerSingle { set; get; }
            public string answerMultiple { set; get; }
            public bool answerTOF { set; get; }
            public string answerContent { set; get; }
        }

//stuAnswerArr 注意前后台变量名称一定要相同
public ActionResult SubmitStuAnswers(List<stuAnswerEntity> stuAnswerArr)
{
    bool re = false;
    List<stuAnswerEntity> stuAnswerEntityList = new List<stuAnswerEntity>();
    stuAnswerEntityList = stuAnswerArr;
    //此时stuAnswerArr中就存有前台stuAnswerArr中的数据；
    return Content(re.ToString());
}

 2. 方法二：js模拟form 进行post提交

　　

　　1) 客户端js代码：

function REV_SubmitStuAnswersBtn() {
    var stuAnswerArr=JSON.stringify(GetQAS());//转成json字符串
    //JS模拟post提交
    var REVQForm = document.createElement("form");
    REVQForm.setAttribute("method", 'POST');
    REVQForm.setAttribute("action", '../Paper/GetREVPaper');
    REVQForm.innerHTML = "";
    var stuAnswerInput = document.createElement("input");
    stuAnswerInput.setAttribute("type", "hidden");
    stuAnswerInput.setAttribute("name", 'REVQ');//'REVQ'
    stuAnswerInput.setAttribute("value", stuAnswerArr);
    REVQForm.appendChild(stuAnswerInput);

    document.body.appendChild(REVQForm);
    REVQForm.submit();
}

 　　

2) 服务端C#代码：以json字符串的方式传输

public ActionResult GetREVPaper()
{
    bool re = false;
    string stuAnswerJson = Request["REVQ"] == null ? "" : Request["REVQ"];//'REVQ'
    //将json字符串反序列化
    List<stuAnswerEntity> studentAnswerList = JsonConvert.DeserializeObject<List<stuAnswerEntity>>(stuAnswerJson);

    return Content(re.ToString());
}
