Web窗体和MVC应用程序在SQL Server中存储数据时引发内部服务器错误500

Question

I am probably repeating same issue discussed on forum but I think this issue should be discussed as it persist with many ways I tried. 我可能会重复在论坛上讨论的同一问题，但我认为应该讨论此问题，因为它以我尝试过的许多方式持续存在。

I have referred number of links including 我已提及了一些链接，包括

Here first one works for me but second is not working so tried it with WebForm and MVC with and without [System.Web.Script.Services.ScriptService]. 在这里，第一个对我有用，但是第二个对我不起作用，因此无论是否使用[System.Web.Script.Services.ScriptService]，都可以使用WebForm和MVC对其进行尝试。 Virtually, It became hit and trail case for me. 实际上，这对我来说成了偶然的案例。 Also, my Fiddler Tool says JSON is correctly supplied in every case when I tried single value or multiple. 另外，我的Fiddler工具说，当我尝试单个值或多个值时，在每种情况下都可以正确提供JSON。 Last but not least there are lots of resources over the web that how achieve AJAX jQuery but merely some specific thing I found how to debug with Inter Server Error. 最后但并非最不重要的一点是，网络上有很多资源可以实现AJAX jQuery，但是我发现了一些特定的东西，可以通过Inter Server Error进行调试。 Any note will be appreciable. 任何笔记将是可观的。

In my ASP.NET MVC application 在我的ASP.NET MVC应用程序中

Services is Like : 服务就像：

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    [System.Web.Script.Services.ScriptService]
    public class SaveDb : System.Web.Services.WebService
    {

        [WebMethod]
        public string InsertIntoDB(string p)
        {
            try
            {
                SqlConnection sqlConnection = new SqlConnection("Data Source=127.0.0.1;Initial Catalog=School;Integrated Security=True");
                sqlConnection.Open();

                SqlCommand sqlCommand = new SqlCommand("insert into UserNamePassword values('uNm1','" + p + "')");
                sqlCommand.ExecuteNonQuery();

                sqlConnection.Close();

            }
            catch (Exception)
            {
                return "Error";
            }

            return "success";
        }
    }

HTML View is Like : HTML视图就像：

@{
    Layout = null;
}

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <script src="jquery.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">
    </script>
    <script type="text/javascript">

        $(document).ready(function () {
            $('#btn').on('click', function (e) {

                e.preventDefault();
                var p = $('#p1').val();

                var jsonData = JSON.stringify({ p: p });

                $.ajax({
                    type: "POST",
                    url: 'MVCP/SaveDb.asmx/InsertIntoDB',
                    data: jsonData,
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: OnSuccess,
                    error: OnErrorCall
                })

                function OnSuccess(response) {
                    var result = response.d;
                    if (result == "success") {
                        alert('Job Done');
                    }
                }

                function OnErrorCall(response) {
                    alert('failed agin');
                }
            })
        })

    </script>
</head>
<body>
    User Name
    <br />

    Password <input id="p1" type="text" />
    <br />

    <button id="btn">Click</button>
</body>
</html>

Note : Putting a break point over the Service Page is not received control and Explicitly loading the Service on Browser and passing the p Parameter worked. 注意：不能在服务页面上放置一个断点，并且无法在浏览器上显式加载该服务并传递有效的p参数。 So, I guess guess Err is coming from Web Service Part thus adding Web Service Tag/ WCF. 因此，我猜想Err来自Web服务部分，从而增加了Web服务标签/ WCF。
