一个FileUpload类库 支持下 欢迎大家提出意见和建议
今天出于项目需要 之前的类库出现很多冗余代码 闲暇之余自己下了一个FilesUpload类库 个人感觉而不错 欢迎大家提出建议
调用代码：string str = "UpLoadFile/Img"; FilesUpload UpMain = new FilesUpload(); UpMain.FileUploadControl = FileUpload1; //设定上传的目录，成功后为存贮的路径“UpLoadFile/Img/************************.jpg” UpMain.UpLoadFilePath = str; //限定文件的格式必须以’|‘隔开 UpMain.AllowUpLoadFileExtension = ".zip|.jpg"; //设定文件的命名方式FilesUpload.RenameType 枚举类型，Guid：guid命名规则，Default：原文件命名规则（如果重复则为原文件命名+i，i为重复的个数），TimeNumber 时分秒毫秒命名规则（yyyyMMddhhmmssfff） //UpMain.RenameTypeList = FilesUpload.RenameType.TimeNumber; UpMain.UpLoad(); if (UpMain.UpLoadSuccess) { //成功后返回的文件扩展名（.jpg） //UpMain.UpLoadFileExtension //成功后返回的文件的存贮路径 “UpLoadFile/Img/************************.jpg” //UpMain.UpLoadFilePath //上传文件的大小 字节为单位 int i = UpMain.UploadFileSize; MessageBox.Show(Page, "上传成功！"); } else {
//失败时候的错误信息 //UpMain.UploadFileErrorMsg MessageBox.Show(Page, UpMain.UploadFileErrorMsg); }
