字符串的长度超过上maxJsonLength属性设置的值。在MVC3 [英] The length of the string exceeds the value set on the maxJsonLength property. in MVC3

问题描述

MVC3（.cshtml文件）

MVC3 (.cshtml File)

$.getJSON(URL, Data, function (data) {

                    document.getElementById('divDisplayMap').innerHTML = data;

                    if (data != null) {
                        $('#myTablesId').show();
                        tdOnclickEvent();

                    }
                    else {
                        $('#myTablesId').hide();
                    }
                }).error(function (xhr, ajaxOptions, thrownError) { debugger; });

在服务器端

 public JsonResult ZoneType_SelectedState(int x_Id, int y_Id)
    {
    JsonResult result = new JsonResult();
     result.Data = "LongString";//Longstring with the length mention below
    return Json(result.Data,"application/json", JsonRequestBehavior.AllowGet);
    }

从服务器端我传递与1194812和超过该长度的字符串。
但我得到的错误说法。

from the server side i am passing the string with the length of 1194812 and more than that. but i am getting the error saying the

"Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

请帮我出ASP

推荐答案

您可以写一个自定义的ActionResult，这将允许您指定数据串行器能够处理的最大长度：

You could write a custom ActionResult which will allow you to specify the maximum length of data that the serializer can handle:

public class MyJsonResult : ActionResult
{
    private readonly object data;
    public MyJsonResult(object data)
    {
        this.data = data;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        var response = context.RequestContext.HttpContext.Response;
        response.ContentType = "application/json";
        var serializer = new JavaScriptSerializer();
        // You could set the MaxJsonLength to the desired size - 10MB in this example
        serializer.MaxJsonLength = 10 * 1024 * 1024;
        response.Write(serializer.Serialize(this.data));
    }
}

，然后使用它：

public ActionResult ZoneType_SelectedState(int x_Id, int y_Id)
{
    string data = "LongString";//Longstring with the length mention below;
    return new MyJsonResult(data);
}

这篇关于字符串的长度超过上maxJsonLength属性设置的值。在MVC3的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
