在 C# 中解析带有文字的文本文件

Question

我在解析带有文字的文本文件时遇到问题。

我遇到问题的文字是：

"\(" which is an open bracket "(" and "/)" which is the close bracket ")"

这是我正在解析的文本文件的示例：

如果您查看第 20 行，产品名称是 Zeal (I)。负数（最后一列应付金额）也用方括号括起来。

我正在逐行解析文本文件，但是，当我尝试

line.Replace(@"\(", "");

这似乎行不通。我以前从未在文件中遇到过这些文字，所以我不确定如何处理。除了这个，我几乎完成了解析。

我这样做的方式非常简单

                string line;
                int count = 0; // to be removed. Used in testing to cap count.
                while ((line = reader.ReadLine()) != null)
                {
                    if (count <= 10)
                    {
                        if (line.Length > 170 && line.Length < 200)
                        {
                            if (!ContainsAny(line))
                            {

                                line.Replace(@"\(", "");

                                indexStart = line.IndexOf("Td (") + 4;

                                col0 = line.Substring(indexStart, 9);
                                col1 = line.Substring(indexStart + 10, 4);
                                col2 = line.Substring(indexStart + 15, 10);
                                col3 = line.Substring(indexStart + 26, 2);
                                col4 = line.Substring(indexStart + 29, 6);
                                col5 = line.Substring(indexStart + 36, 8);
                                col6 = line.Substring(indexStart + 45, 5);
                                col7 = line.Substring(indexStart + 51, 2);
                                col8 = line.Substring(indexStart + 54, 4);
                                col9 = line.Substring(indexStart + 59, 10);
                                col10 = line.Substring(indexStart + 70, 2);
                                col11 = line.Substring(indexStart + 73, 10);
                                col12 = line.Substring(indexStart + 84, 6);
                                col13 = line.Substring(indexStart + 91, 7).Replace("$", "");
                                col14 = line.Substring(indexStart + 99, 7);
                                col15 = line.Substring(indexStart + 107, 7).Replace("%", "");
                                col16 = line.Substring(indexStart + 115, 12);

                                MessageBox.Show(string.Format("{0}; {1}; {2}; {3}; {4}; {5}; {6}; {7}; {8}; {9}; {10}; {11}; {12}; {13}; {14}; {15}; {16};", col0, col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11, col12, col13, col14, col15, col16));


                                //writer.WriteLine(lineOut);


                                count += 1; // to be removed. Used in testing to cap count.
                            }
                        }
                    }

Answer 1

line.Replace(@"\(", ""); 不修改 string。它只是 return 新更改 string。你应该写：

line = line.Replace(@"\(", "");

检查 String.Replace 的文档：

Returns a new string in which all occurrences of a specified string in the current instance are replaced with another specified string.

Answer 2

您需要使用：

line=line.Replace(@"\(", "");

Answer 3

看起来你写的比实际需要的太多了。

        var allLines = File.ReadAllLines(@"C:\myfile.text");
        var correctedLines = allLines.Select(l => l.Replace(@"\(", "").Replace(@"\)", ""));
        //now use corrected lines in your code
