Winform窗体程序 如何将用户设置文件放到资源文件读取和写入

文件作为资源文件编译然后读取还是比较容易的。但是要运行时动态读出进行修改再编译回去，那很麻烦，特别象你的要求可能是想做成单文件吧，那时程序还是载入内存的，默认情况下可能还是不能修复的。

如果想做成单文件的话，你看看一些软件虚拟工具，可以将程序打包成一个单文件进行运行的，不知能不能满足你的要求。

C#实现访问网络共享文件夹，使用 WNetAddConnection2A 和 WNetCancelConnection2A。

在目标服务器建立共享文件夹，建立访问账号test

return ret

}

public static int Disconnect (string localpath)

{

return WNetCancelConnection2A(localpath, 1, 1)

}

调用方式：

public static void TestNetWorkConnection()

{

string localpath = "X:"

//int status = NetworkConnection.Connect(@"\\192.168.0.2\test", localpath, @"test", "test")

int status = NetworkConnection.Connect("\\\\192.168.0.2\\test", localpath, @"test", "test")

if (status == (int)ERROR_ID.ERROR_SUCCESS)

{

FileStream fs = new FileStream(localpath + @"\\123.txt", FileMode.OpenOrCreate)

using (StreamWriter stream = new StreamWriter(fs))

{

stream.WriteLine("你好呀，成功了")

stream.Flush()

stream.Close()

}

fs.Close()

}

else

{

Console.WriteLine(status)

}

NetworkConnection.Disconnect(localpath)

}

下载的时候请是用文件流··

如果服务器设置了关闭ping的方法。

就很难实现了·

你是想读取独立存储器中的数据吗？

以下是读取独立存储器的方法：

1：决定需要使用哪种范围的独立存储器。

2：调用IsolateSotrageFile类对应的方法返回独立存储器实例。

例如：IsolateSotrageFileisoFile = IsolateStorageFile.GetUserStoreForDomain()

3：使用搜索的方法GetFileNames()判断对应的文件是否在独立存储器中存在。

4：如果文件存在则根据对应的文件名创建IsolateStorageFileStream对象。

创建IsolateStorageFileStream对象如下：

IsolateStorageFileStreamisoStream = new IsolateStorageFileStream(“test.txt”, FileMode.Open,isoFile)

第三个参数为IsolateStorageFIle实例，该参数告诉IsolateStorageFileStream对象从指定的独立存储器中创建流。

5：使用以上步骤中创建好的isoStream来创建StreamReader。

例如：

StreamReadersr = new StreamReader(isoStream)

6：创建好StreamReader对象后就可以像读取普通文件那样读取独立存储器中的文件了。

7：读取完成后需要关闭以下对象来释放资源，使用对应的close()方法。StreamReader,IsolateStorageFileStream,IsolateStoreFile。
