初始化奖池

//简单点，没有做递归查找图片
            pictureList.Clear();
            nameList.Clear();
            try
            {
     
                DirectoryInfo folder = new DirectoryInfo(_ImagePath);

                FileInfo[] fiArr1 = folder.GetFiles("*.jpg");
                InitArrs(fiArr1);

                FileInfo[] fiArr2 = folder.GetFiles("*.png");
                InitArrs(fiArr2);

                FileInfo[] fiArr3 = folder.GetFiles("*.bmp");
                InitArrs(fiArr3);

                if (null == nameList || nameList.Count < 1)
                {
     
                    bError = true;
                    MessageBox.Show(_TipError);
                    return;
                }
                if (nameList.Count == 1)
                {
     
                    bError = true;
                    MessageBox.Show(_TipOnlyOne);
                    return;
                }

                //初始化成功后默认显示第一个
                this.picEmp.Image = this.pictureList[p1];
                this.lblEmpName.Text = this.nameList[p1];
            }
            catch (Exception)
            {
     
                bError = true;
                MessageBox.Show(_TipError);
                return;
            }

private void InitArrs(FileInfo[] fiArr1)
        {
     
            if (null != fiArr1 && fiArr1.Length > 0)
            {
     
                foreach (FileInfo file in fiArr1)
                {
     
                    nameList.Add(file.Name.Substring(0, file.Name.IndexOf('.')));
                    pictureList.Add(Image.FromFile(file.FullName));
                }
            }
        }
