C# winform把本地文件上传到服务器上，和从服务器上下载文件
昨天在做项目过程中遇到需要把本地文件上传到服务器上的问题，在这里记录一下，方便大家互相学习！
/// <summary>
/// 上传文件方法
/// </summary>
/// <param
name="filePath">本地文件所在路径（包括文件）</param>
/// <param
name="serverPath">文件存储服务器路径（包括文件）</param>
public void
UploadFile(string filePath, string serverPath)
{
//创建WebClient实例
WebClient webClient = new
WebClient();
webClient.Credentials =
CredentialCache.DefaultCredentials;
//要上传的文件
FileStream fs = new FileStream(filePath, FileMode.Open,
FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[]
postArray = br.ReadBytes((int)fs.Length);
Stream postStream =
webClient.OpenWrite(serverPath, "PUT");
try
{
if
(postStream.CanWrite)
{
postStream.Write(postArray, 0,
postArray.Length);
postStream.Close();
fs.Dispose();
}
else
{
postStream.Close();
fs.Dispose();
}
}
catch (Exception
ex)
{
postStream.Close();
fs.Dispose();
throw
ex;
}
finally
{
postStream.Close();
fs.Dispose();
}
}
/// <summary>

/// </summary>
/// <param name="serverPath">被下载的文件地址（服务器地址包括文件）</param>
/// <param name="filePath">另存放的路径（本地需要存储文件的文件夹地址）</param>
public void Download(string serverPath, string filePath)
{
WebClient client = new WebClient();
string fileName =
serverPath.Substring(serverPath.LastIndexOf("/") + 1); ;//被下载的文件名
string path = filePath + fileName;//另存为地址
try
{
WebRequest myre =
WebRequest.Create(serverPath);
}
catch (Exception
ex)
{
MessageBox.Show(ex.Message,
"Error");
}
try
{
client.DownloadFile(serverPath,
fileName);
FileStream fs = new FileStream(fileName, FileMode.Open,
FileAccess.Read);
BinaryReader r = new BinaryReader(fs);
byte[]
mbyte = r.ReadBytes((int)fs.Length);
FileStream fstr = new
FileStream(path, FileMode.OpenOrCreate,
FileAccess.Write);
fstr.Write(mbyte, 0,
(int)fs.Length);
fstr.Close();
}
