C#應用Socket上傳並保留圖片的辦法

C#應用Socket上傳並保留圖片的辦法。本站提示廣大學習愛好者：（C#應用Socket上傳並保留圖片的辦法）文章只能為提供參考，不一定能成為您想要的結果。以下是C#應用Socket上傳並保留圖片的辦法正文

本文實例講述了C#應用Socket上傳並保留圖片的辦法。分享給年夜家供年夜家參考。具剖析以下：

應用string filename = openFile.FileName;即前往帶全途徑的文件名 Path.GetFileNameWithoutExtension(filename)便可取得不領路徑、後綴名的文件名。 上傳圖片應用二進制 tcp協定上傳的
