调用上传文件方法:

UpLoadFile(@"D:\沙盘采集与控制电路接线表.xls", @"\\10.0.0.35\sand_File_Manage\9", "Administrator", "Huawei12#$")

上传文件的方法:

//上传文件:要设置共享文件夹是否有创建的权限,否则无法上传文件  
public void UpLoadFile(string fileNamePath, string urlPath, string User, string Pwd)
{
string newFileName = fileNamePath.Substring(fileNamePath.LastIndexOf(@"\") + 1);//取文件名称

if (urlPath.EndsWith(@"\") == false) urlPath = urlPath + @"\";

urlPath = urlPath + newFileName;

WebClient myWebClient = new WebClient();
NetworkCredential cread = new NetworkCredential(User, Pwd, "Domain");
myWebClient.Credentials = cread;
FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.Read);
BinaryReader r = new BinaryReader(fs);

try
{
byte[] postArray = r.ReadBytes((int)fs.Length);
Stream postStream = myWebClient.OpenWrite(urlPath);
// postStream.m
if (postStream.CanWrite)
{
postStream.Write(postArray, 0, postArray.Length);
MessageBox.Show("文件上传成功!", "提醒", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
MessageBox.Show("文件上传错误!", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}

postStream.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "错误");
}

}
}
