wcf – 如何将字节数组从silverlight保存到文件中

http://www.silverlightshow.net/items/Using-the-SaveFileDialog-in-Silverlight-3.aspx

在回调方法中,您可以实现写入文件的逻辑 – 首先打开对话框,然后获取指向文件流的指针,如下所示.

try 
       {
           byte[] fileBytes = //your bytes here 
           SaveFileDialog dialog=new SaveFileDialog();

           //Show the dialog              
           bool? dialogResult = this.dialog.ShowDialog();  

           if (dialogResult!=truE) return;


            //Get the file stream

            using ( Stream fs = ( Stream )this.dialog.openFile() )  
            {  
                fs.Write( fileBytes,fileBytes.Length );  
                fs.Close();  

                //File successfully saved
            }  
        }  
        catch ( Exception ex )  
        {  
            //inspect ex.message  
        }
