Question

我想在文本文件中添加页眉和页脚。我怎样才能做到这一点？我的目标应该是这样的：

 tr.AddHeaderAndFooter("Header","footer";

例如：

using (var fileStream = new FileStream(ConfigurationManager.AppSettings["TargetDir"] + swiftFile, FileMode.Open, FileAccess.Read))
{
    TextReader tr = new StreamReader(fileStream);
    tr.AddHeaderAndFooter("Header","footer";
}

Answer 1

.txt文件没有页眉或页脚。
但您可以使用以下代码示例模拟此行为：

// since there is no predefined method to add a string into the beginning   
// of a file, you have to first read the whole file content into a temporary 
// variable
string currentContent = String.Empty;
if (File.Exists(filePath))
{
    currentContent = File.ReadAllText(filePath);
}

// now you can put your header into the beginning of the file so:
string header = "My Header";
File.WriteAllText(filePath, header + Environment.NewLine + currentContent );

// and finally you use the append method to add footer to the end of the file
string footer = "My Footer";
File.AppendAllText(filepath, Environment.NewLine + footer);

Answer 2

你的意思是：

string text = "header" + Environment.NewLine + "rest of file ... asjdhakjdh" + Environment.NewLine + "footer";
File.WriteAllText("filename.txt", text);

这将保存

头

其余文件...... asjdhakjdh

页脚

在名为 filename.txt的 .txt 文件中

因此，您可以读取文件，将其存储在字符串中，添加页眉和页脚行，然后将其写回到它所来自的文件中。

如何在C＃中添加页眉和页脚txt文件？
