C# 调用WinRAR解压缩文件

在项目中有可能会用到解压缩，代码如下
public class CompressHelper
    {
        
        /// <summary>
        /// 压缩
        /// </summary>

        /// <param name="compressName">压缩文件名</param>
        /// <param name="compressPath">压缩文件路径</param>
        /// <returns></returns>
        public static bool CompressFile(string sourceFilePath, string sourceName, string compressName, string compressPath)
        {
            string winrarPath = string.Empty;
            if (!ExistsCompressApp(out winrarPath))
            {
                return false;
            }
            if (string.IsNullOrEmpty(compressPath))
            {
                compressPath = sourceFilePath;
            }
            string type = compressName.Substring(compressName.IndexOf('.') + 1);
            string compressType = string.Empty;
            if (type.ToUpper() == CompressType.RAR.ToString())
            {
                compressType = "-af" + CompressType.RAR.ToString().ToLower();
            }
            else if (type.ToUpper() == CompressType.ZIP.ToString())
            {
                compressType = "-af" + CompressType.ZIP.ToString().ToLower();
            }
            else
            {
                compressType = "-af" + CompressType.RAR.ToString().ToLower();
