前端技术 2023/09/01 .NET

复制代码 代码如下:

HttpPostedFile UpFile = File1.PostedFile;
int FileLenght = UpFile.ContentLength;
decimal FileSize = FileLenght / 1024;
if (FileLenght == 0)
{
    DIVShowGVError.Visible = true;
    LblShowGVError.Text = \"请选择上传文件\";
    return;
}
string strImageName = UpFile.FileName;
string strImageType = strImageName.Substring(strImageName.LastIndexOf(\".\")).ToLower();
if (strImageType != \".jpg\" && strImageType != \".jpeg\" && strImageType != \".bmp\" && strImageType != \".png\")
{
    DIVShowGVError.Visible = true;
    LblShowGVError.Text = \"請上傳以下文件格式的圖片:jpg,jpeg,bmp,png\";
    return;
}
if (FileSize > 2048)
{
    DIVShowGVError.Visible = true;
    LblShowGVError.Text = \"上傳圖片不能大於2M\";
    return;
}
else
{
    Byte[] FileByteArray = new Byte[FileLenght];
    Stream StreamObject = UpFile.InputStream;
    StreamObject.Read(FileByteArray, 0, FileLenght);

    strNewLeave = \"insert into [Leave]([ID],[EmployeeNo],[AgentID],[LeaveType],[StartDate],[EndDate],[Hours],[LeaveReason],[ReportTime],[ReportID],[ImageName],[ImageData]) \";
    strNewLeave += \"values(@LeaveNo,@EmpNo,@AgentName,@LeaType,@StartDate,@EndDate,@Hours,@Reason,getdate(),@Admin,@ImageName,@Image) \";

    sqlPara = new SqlParameter[] {
    new SqlParameter(\"@LeaveNo\",strLeaNo),
    new SqlParameter(\"@EmpNo\",strEmpNo),
    new SqlParameter(\"@AgentName\",strAgentID),
    new SqlParameter(\"@LeaType\",strLeaType),
    new SqlParameter(\"@StartDate\",strDateSt),
    new SqlParameter(\"@EndDate\",strDateEnd),
    new SqlParameter(\"@Hours\",strHours),
    new SqlParameter(\"@Reason\",strReason),
    new SqlParameter(\"@Admin\",strAdmin),
    new SqlParameter(\"@ImageName\",strImageName),
    new SqlParameter(\"@Image\",FileByteArray)
    };

    StreamObject.Close();
}
