c#-dicom文件与jpg互相转换

最近在搞DICOM和JPG文件的互相转换，查了很多资料也没得到想要的，最终也算是摸索着使用C#完成了dicom和jpg文件互相转换，在这里简单的将代码记录一下(c#控制台程序),依赖fo-dicom

Dcm2JpgOptions

用来接收存放控制台传入的命令参数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DcmUtil
{
    class Dcm2JpgOptions
    {

        /// <summary>
        /// dcm路径
        /// </summary>
        public string dcmPath { get; set; }
        /// <summary>
        /// jpg图片输出目录
        /// </summary>
        public string outJpgDir { get; set; }
    }
}

Img2DcmOptions

用来接收存放控制台传入的命令参数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DcmUtil
{
    class Img2DcmOptions
    {
        /// <summary>

        /// 图片集合
        /// </summary>
        public List<String> images { get; set; }
    }
}

DcmScuOptions

用来接收存放控制台传入的命令参数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DcmUtil
{
    class DcmScuOptions
    {

        /// <summary>
