小编G G*_* Gr的帖子

谁能给我一个贝叶斯网络和模糊逻辑用于入侵检测的例子？

我正在努力弄清楚如何使用它.还有任何代码吗？

多谢你们.

我试图从Web服务获取列表的总和.

[WebMethod]
public string CalculateSum(List<int> listInt)
{
       int[] sum = listInt.ToArray();

        return sum; // error under sum on this line

}

但我得到的错误无法将int转换为字符串,这应该有用吗？

客户代码:

    public partial class Form1 : Form
    {
        List<int> listInt = new List<int>();

        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {

        }
        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            listInt.Add(Convert.ToInt32(textBox1.Text));
            textBox1.Clear();
            listBox1.Items.Clear();
            for (int i = 0; i < listInt.Count; i++)
            {
                listBox1.Items.Add(listInt[i]);
            }
        }

        private …

嗨,我得到这个代码:不能将类型字符串转换为int.

        CalculateSumOfList.ServiceReference1.Service1SoapClient client = new CalculateSumOfList.ServiceReference1.Service1SoapClient();
        CalculateSumOfList.ServiceReference1.ArrayOfInt arrayOfInt = new CalculateSumOfList.ServiceReference1.ArrayOfInt();
        arrayOfInt.AddRange(listInt);
        int result = client.CalculateSum(arrayOfInt); //error here!
        label1.Text = Convert.ToString(result);

我打电话的网络方法在这里:

namespace CalculateWebServiceSum
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [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 Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string CalculateSum(List<int> listInt)
        {
            int[] sum = listInt.ToArray();

            return sum.ToString();

        } …

我收到错误并非所有代码路径都返回值？

    public string Authentication(string studentID, string password) // this line?
    {
        var result = students.FirstOrDefault(n => n.StudentID == studentID);
        //find the StudentID that matches the string studentID 
        if (result != null)
        //if result matches then do this
        {
            //---------------------------------------------------------------------------- 
            byte[] passwordHash = Hash(password, result.Salt);
            string HashedPassword = Convert.ToBase64String(passwordHash);
            //----------------------------------------------------------------------------
            // take the specific students salt and generate hash/salt for string password (same way student.Passowrd was created)

            if (HashedPassword == result.Password)
            //check if the HashedPassword (string password) matches the stored student.Password …

应用此方法时:

%% When an outlier is considered to be more than three standard deviations away from the mean, use the following syntax to determine the number of outliers in each column of the count matrix:

mu = mean(data)
sigma = std(data)
[n,p] = size(data);
% Create a matrix of mean values by replicating the mu vector for n rows
MeanMat = repmat(mu,n,1);
% Create a matrix of standard deviation values by replicating the sigma vector for n rows
SigmaMat = …

是否可以在matlab中反转以下内容:

[U,S,V]=svds(fulldata,columns);

有人可以帮我转换成c#吗？

似乎无法解决此错误:
