我正在尝试创建一个程序来替换.txt文件中的字符串。继承人的伎俩。如果选中它们，我将替换文件中的字符串，但当我做一个替代检查时，它仍然取代了另一个。

    private void BatchReplace()
    {
        string sourceFolder = FilePath.Text;
        string searchWord = Searchbar.Text;

        DateTime now = DateTime.Now;

        List<string> allFiles = new List<string>();
        AddFileNamesToList(sourceFolder, allFiles);
        if (listView1.CheckedItems.Count != 0)
        {
            foreach (String file in allFiles)
            {
                for (int x = 0; x <= listView1.CheckedItems.Count - 1; x++)
                {
                    if (file.Contains(listView1.CheckedItems[x].Text))
                    {
                        MessageBox.Show("File contains: " + listView1.CheckedItems[x].Text);
                        try
                        {
                            DialogResult dialogResult = MessageBox.Show("Are you sure you want to replace \"" + Searchbar.Text + "\" with \"" + Replacebar.Text + "\"?", "WARNING!", MessageBoxButtons.YesNo);
                            if (dialogResult == DialogResult.Yes)
                            {
                                StreamReader reader = new StreamReader(file);
                                string content = reader.ReadToEnd();
                                reader.Close();

                                content = Regex.Replace(content, Searchbar.Text, Replacebar.Text);
                                StreamWriter writer = new StreamWriter(file);
                                writer.Write(content); writer.Close();
                            }
                            else
                            {
                            }
                        }
                        catch
                        { 
                        } 
                        }
                    }
                }
            }
        }
        else
        {
        MessageBox.Show("Please Check the files you want to rename");
        }
    }
   public static void AddFileNamesToList(string sourceDir, List<string> allFiles)
    {

        string[] fileEntries = Directory.GetFiles(sourceDir);

        try
        {
            foreach (string fileName in fileEntries)
            {
                allFiles.Add(fileName);
            }

            //Recursion    
            string[] subdirectoryEntries = Directory.GetDirectories(sourceDir);
            foreach (string item in subdirectoryEntries)
            {
                // Avoid "reparse points"
                if ((File.GetAttributes(item) & FileAttributes.ReparsePoint) != FileAttributes.ReparsePoint)
                {
                    AddFileNamesToList(item, allFiles);
                }
            }
        }

我仍然对你要做的事情感到困惑，但为了简化事情，为什么不在你用ListView填充目录中的文件时添加文件路径（或文件） object）到ListViewitem的标记属性？

这样，当您遍历选中的项目时，您可以直接检索文件，而不必一次遍历两个列表。

类似的东西：

    private void BatchReplace()
    {
        string sourceFolder = FilePath.Text;
        string searchWord = Searchbar.Text;

        AddFileNamesToList(sourceFolder);
        if (listView1.CheckedItems.Count == 0)
        {
            MessageBox.Show("Please Check the files you want to rename");
            return;
        }


                for (int x = 0; x < listView1.CheckedItems.Count; x++)
                {
                    var file = listView1.CheckedItems[x].Tag.ToString()
                        try
                        {
                            DialogResult dialogResult = MessageBox.Show("Are you sure you want to replace \"" + Searchbar.Text + "\" with \"" + Replacebar.Text + "\"?", "WARNING!", MessageBoxButtons.YesNo);
                            if (dialogResult == DialogResult.Yes)
                            {
                                StreamReader reader = new StreamReader(file);
                                string content = reader.ReadToEnd();
                                reader.Close();

                                content = Regex.Replace(content, SearchWord, Replacebar.Text);
                                StreamWriter writer = new StreamWriter(file);
                                writer.Write(content); 
                                writer.Close();
                            }
                        }
                        catch
                        { 
                        } 
                    }
                }
            }

对于缩进很抱歉，如果这不能直接工作，我还没有测试过。
