WebService端代码

复制代码 代码如下:

/// <summary>

/// 上传文件到远程服务器

/// </summary>

/// <param name="fileBytes">文件流</param>

/// <param name="fileName">文件名</param>

/// <returns>字符串</returns>

[WebMethod(Description = "上传文件到远程服务器.")]

public string UploadFile(byte[] fileBytes, string fileName)

{

try

{

MemoryStream memoryStream = new MemoryStream(fileBytes); //1.定义并实例化一个内存流，以存放提交上来的字节数组。

FileStream fileUpload = new FileStream(Server.MapPath(".") + "" + fileName, FileMode.Create); ///2.定义实际文件对象，保存上载的文件。

memoryStream.WriteTo(fileUpload); ///3.把内存流里的数据写入物理文件

memoryStream.Close();

fileUpload.Close();

fileUpload = null;

memoryStream = null;

return "文件已经上传成功";

}

catch (Exception ex)

{
