编写一个文件，添加随机字符到每行的开头(Writing a file adding random characters to start of each line)

我在Windows Phone 7中使用C＃覆盖文件。当我这样做时，每行的开头都会添加一个看似随机的字符。

这是为什么发生？

码：

public static bool overwriteFile(string filename, string[] inputArray) { try { IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication(); FileStream stream = store.OpenFile(filename, FileMode.Create); BinaryWriter writer = new BinaryWriter(stream); foreach (string input in inputArray) { writer.Write(input + "\n"); } writer.Close(); return true; } catch (IOException ex) { return false; } }

洛代码：

public static Idea[] getFile(string filename) { try { IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication(); string fileContents = null; if (store.FileExists(filename)) // Check if file exists { IsolatedStorageFileStream save = new IsolatedStorageFileStream(filename, FileMode.Open, store); StreamReader streamReader = new StreamReader(save); fileContents = streamReader.ReadToEnd(); save.Close(); } string[] lines = null; if (fileContents != null) { lines = fileContents.Split('\n'); } Idea[] ideaList = null; if (lines != null) { ideaList = new Idea[lines.Length]; for (int i = 0; i < lines.Length; i++) { ideaList[i] = new Idea(lines[i].TrimEnd('\r')); } } return ideaList; } catch (IOException ex) { return null; } }

I'm overwriting a file using C# in Windows Phone 7. When I do this a seemingly random character is added to the start of each line.

Why is this happening?

Code:

public static bool overwriteFile(string filename, string[] inputArray) { try { IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication(); FileStream stream = store.OpenFile(filename, FileMode.Create); BinaryWriter writer = new BinaryWriter(stream); foreach (string input in inputArray) { writer.Write(input + "\n"); } writer.Close(); return true; } catch (IOException ex) { return false; } }

Lodaing Code:

public static Idea[] getFile(string filename) { try { IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication(); string fileContents = null; if (store.FileExists(filename)) // Check if file exists { IsolatedStorageFileStream save = new IsolatedStorageFileStream(filename, FileMode.Open, store); StreamReader streamReader = new StreamReader(save); fileContents = streamReader.ReadToEnd(); save.Close(); } string[] lines = null; if (fileContents != null) { lines = fileContents.Split('\n'); } Idea[] ideaList = null; if (lines != null) { ideaList = new Idea[lines.Length]; for (int i = 0; i < lines.Length; i++) { ideaList[i] = new Idea(lines[i].TrimEnd('\r')); } } return ideaList; } catch (IOException ex) { return null; } }
