[webmethod(description="上傳并保存圖片文件")]
public bool savefile(byte[] bindata,string filename){
bool success=false;
string savepath=system.configuration.configurationsettings.appsettings["uploaddirectory"];
if(savepath==null) savepath="photo";
if(savepath.indexof("://")<0) savepath=server.mappath(savepath);//不是絕對路徑
if(!savepath.endswith("//")) savepath += "//";
if(!directory.exists(savepath)){
throw new exception("服務器端沒有找到有效的保存路徑！");
}
filestream filestream=null;
try{
filestream=new filestream(savepath + filename,filemode.create,fileaccess.write);
//write the file
filestream.write(bindata,0,bindata.length);
filestream.flush();//clear the buffer,write the data to the hard disk
success=true;
}catch(exception ex){
throw new exception(ex.message);
}finally{
filestream.close();
}
return success;
}
解決思路：編寫webservice過程savefile(byte[] bindata,string filename0;
客戶端直接用調用，把數據流作參數傳上來就完了。
