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

/// <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();
}
}
