正则表达式替换的问题

我正在尝试制作一个程序来浏览很多.sql文件,并将例如view_name的名称替换为[dbo]。[view_name]。到目前为止,它取代了大多数单词,但是如果名称包含括号中的数字,如(3)或(7)等等,它将不会替换该文件中的任何内容。我已经提供了以下代码。

        FolderBrowserDialog fb = new FolderBrowserDialog();
        fb.ShowDialog();

        string directory = fb.SelectedPath;

        if(directory != String.Empty)
        {
            DirectoryInfo di = new DirectoryInfo(directory);
            FileInfo fi = new FileInfo(directory);
            FileInfo[] fiArray = di.GetFiles();

            for (int i = 0; i < fiArray.Length; i++)
            {
                string result;
                //StreamReader
                using (StreamReader sr = new StreamReader(directory + "\\" + fiArray[i].ToString()))
                {
                    string temp = sr.ReadToEnd();

                    string tempNameExtens = fiArray[i].Name;
                    string tempNameNoExtens = Path.GetFileNameWithoutExtension(fiArray[i].Name);
                    MessageBox.Show(tempNameNoExtens);


                    string pattern = "\\s" + tempNameNoExtens;
                    string replace = " [dbo].[" + tempNameNoExtens + "]";

                    Regex rgx = new Regex(pattern);
                    result = rgx.Replace(temp, replace);
                }

                //StreamWriter
                using (StreamWriter sw = new StreamWriter(directory + "\\" + fiArray[i].ToString()))
                {
                    sw.WriteLine(result);
                }
            }
        }

构建正则表达式模式时,您应该Escape个字符:

string pattern = "\\s" + Regex.Escape(tempNameNoExtens);
