C#文件搜索/病毒扫描程序(代码不起作用) [英] C# File Search/Virus Scanner (code not working)

问题描述

我遵循了youtube上的教程: http://www.youtube.com/watch?v= XWlUw_x4ejg& feature = related [ ^ ]

我按照所有步骤操作，并正确复制了所有代码，但是在第48行和第64行(均为第48列)中，我始终遇到错误.该错误显示数组创建必须具有数组大小或数组初始化程序"，我该如何解决?这是代码:

I followed a tutorial on youtube: http://www.youtube.com/watch?v=XWlUw_x4ejg&feature=related[^]

I followed all the steps and copied all the code correctly but I keep getting an error in the code in Line 48 and 64 (both column 48). The error says "Array creation must have array size or array initializer", how do I fix that? Here is the code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Text.RegularExpressions;

namespace Commander_Uzzy_Scanner
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private int viruses = 0;

        private void button1_Click(object sender, EventArgs e)
        {
            folderBrowserDialog1.ShowDialog();
            label1.Text = folderBrowserDialog1.SelectedPath;
            viruses = 0;
            label2.Text = "Viruses: " + viruses.ToString();
            progressBar1.Value = 0;
            listBox1.Items.Clear();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string[] search = Directory.GetFiles(@folderBrowserDialog1.SelectedPath, "*.*");
            progressBar1.Maximum = search.Length;
            foreach (string item in search)
            {
                try
                {
                    StreamReader stream = new StreamReader(item);
                    string read = stream.ReadToEnd();
                    string[] virus = new string[] ("trojan", "virus", "hacker");
                    foreach (string st in virus)
                    {
                        if (Regex.IsMatch(read, st))
                        {
                            MessageBox.Show("Virus Detected!");
                            viruses += 1;
                            label2.Text = "Viruses: " + viruses.ToString();
                            listBox1.Items.Add(item);
                        }
                        progressBar1.Increment(1);
                    }
                }
                catch
                {
                    string read = item;
                    string[] virus = new string[] ("trojan", "virus", "hacker");
                    foreach (string st in virus)
                    {
                        if (Regex.IsMatch(read, st))
                        {
                            MessageBox.Show("Virus Detected!");
                            viruses += 1;
                            label2.Text = "Viruses: " + viruses.ToString();
                            listBox1.Items.Add(item);
                        }
                        progressBar1.Increment(1);
                    }
                }
            }
        }
    }
}

我不知道我是否足够具体！请不要犹豫，询问有关代码提供的问题，尽管我真的是C#的新手.

I don''t know if I have been specific enough! Please don''t hesitate to ask questions about the code provide, although I''m really new to C#

推荐答案

此错误是由于源代码引起的:

This error is due to the source code:

string[] search = Directory.GetFiles(@folderBrowserDialog1.SelectedPath, "*.*");

这行的问题是您创建了一个新的数组搜索"，但没有定义大小.创建数组时，必须定义数组的大小或声明其元素.

希望是这样.

And the problem with this line is that you create a new array ''search'' but you don''t define a size. When you create an array you have to either define a size for the array, or declare its elements.

Hope, it clarifies.

尝试

string[] virus = new string[3] {"trojan", "virus", "hacker"};
