?一。利用webservice上传文件
客户端：
页面：加入一个FileUpload 控件，一个Button(btnUpload)
下面是btnUpload的事件：
?
protected
?
void
?btnUpload_Click(
object
?sender,?EventArgs?e)
????
{????
????????/**/////获得上传文件的名称
????????//FileInfo?file?=?new?FileInfo(fileUpload.PostedFile.FileName);
????????//将上传的文件转换为二进制流
????????byte[]?fileContent?=?fileUpload.FileBytes;
????????//获得上传文件的名称
????????string?fileName?=?fileUpload.FileName;
????????//实例化webservice
????????AdService.Service?adTemp?=?new?AdService.Service();
????????if?(adTemp.UploadFile(fileContent,?fileName)) //调用上传方法。
????????
{
????????????Response.Write("OK");
????????}
????????else
????????
{
????????????Response.Write("error");
????????}
????}
新建一个webService 项目，以下是上传方法的代码：
/**/
///?<summary>
????///?通过WebService上传文件
????///?</summary>
????///?<param?name="fs">文件二进制流</param>
????///?<param?name="fileName">文件名</param>
????///?<returns></returns>
????[WebMethod(Description?
=
?
"
web提供的方法，上传文件到相应的地址
"
)]????
????
public
?
bool
?UploadFile(
byte
[]?fs,?
string
?fileName)
????
{
????????try
????????
{
????????????/**////定义并实例化一个内存流，以存放提交上来的字节数组。
????????????System.IO.MemoryStream?m?=?new?System.IO.MemoryStream(fs);
????????????//取出存放地址，可以通过数据库里存放，不用定死了。此处只是做DEMO。
????????????string?strFile?=?"E:"?+?"//"?+?"Personal?files"?+?"//"?+?"good?things"?+?"//"?+fileName;
????????????/**////定义实际文件对象，保存上载的文件。
????????????System.IO.FileStream?fl?=?new?System.IO.FileStream(strFile,?FileMode.OpenOrCreate);
????????????/**////把内内存里的数据写入物理文件
????????????m.WriteTo(fl);????????????
????????????m.Close();
????????????fl.Close();
????????????m?=?null;
????????????fl?=?null;
????????????return?true;
????????}
????????catch
????????
{
????????????return?false;
????????}
????}
?
二。利用控件上传文件
.aspx页面代码
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
??? <title>无标题页</title>
</head>
<script runat="server">
???
</script>
<body>
??? <form id="form1" runat="server">
??? <div>
??????? <ASP:FileUpload ID="FileUpload1" runat="server" /><br />
<br />
<ASP:Button ID="Button1" runat="server" OnClick="Button1_Click"
?Text="Upload File" /> <br />
<br />
<ASP:RegularExpressionValidator
?id="RegularExpressionValidator1" runat="server"
?ErrorMessage="Only mp3,m3u or mpeg files are allowed!"
//下面的文件类型帅选代码，可以在aspx.cs页面中写更为妥当
?ValidationExpression="^(([a-zA-Z]:)|(//{2}/w+)/$?)(//(/w[/w].*))+(.jpg|.JPG|.mp3|.MP3|.mpeg|.MPEG|.m3u|.M3U)$"
?ControlToValidate="FileUpload1"></ASP:RegularExpressionValidator>
<br />
<ASP:RequiredFieldValidator
?id="RequiredFieldValidator1" runat="server"
?ErrorMessage="This is a required field!"
?ControlToValidate="FileUpload1"></ASP:RequiredFieldValidator>
??????? <br />
??????? <ASP:Label ID="Label1" runat="server"></ASP:Label>
??????? <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></div>
??? </form>
</body>
</html>
aspx.cs页面代码
protected void Button1_Click(object sender,EventArgs e)
??? {
??????? if (FileUpload1.HasFile)
??????? {
???????????
??????????? //string clientpath = FileUpload1.PostedFile.FileName.ToString();???????????
??????????? if(FileUpload1.PostedFile.ContentLength!=0)
???????????? {???????????????
??????????????? try
??????????????? {
??????????????????? string pathfirst = "C://Uploads//" + FileUpload1.FileName;
??????????????????? FileUpload1.SaveAs("C://Uploads//" +
???????????????????????? FileUpload1.FileName);
??????????????????? Label1.Text = "File name: " +
???????????????????????? FileUpload1.PostedFile.FileName + "<br>" +
???????????????????????? FileUpload1.PostedFile.ContentLength + " kb<br>" +
???????????????????????? "Content type: " +
???????????????????????? FileUpload1.PostedFile.ContentType;
??????????????????? string sql = "insert into test(path) values('" + pathfirst + "')";
??????????????????? SqlConnection con = new SqlConnection("Data Source=192.168.1.69;Initial Catalog=calendar;Integrated Security=False;user ID=sa;Password=huison");
??????????????????? SqlCommand com = new SqlCommand(sql,con);
??????????????????? con.Open();
??????????????????? com.ExecuteNonQuery();
??????????????????? con.Close();
??????????????????? Label2.Text = FileUpload1.FileName;
??????????????? }
??????????????? catch (Exception ex)
??????????????? {
??????????????????? Label1.Text = "ERROR: " + ex.Message.ToString();
??????????????? }
??????????? }
??????????? else
??????????? {
??????????????? Label1.Text = "This file does not exist.";
??????????? }
??????? }
??????? else
??????? {
??????????? Response.Write("You have not specified a file.");
??????? }??? }
?
