MD5类(MD5Helper)

项目中经常需要使用到MD5来进行加密

代码:

namespace MyProject.Common
{
    public class MD5Helper
    {
        /// <summary>
        /// 对字符串进行MD5运算
        /// </summary>
        /// <param name="str"></param>
        /// <returns></returns>
        public static string GetMd5String(string str)
        {
            MD5 md5 = MD5.Create();
            byte[] buffer = Encoding.UTF8.GetBytes(str);
            byte[] md5Buffer = md5.ComputeHash(buffer);
            StringBuilder sb = new StringBuilder();
            foreach (byte b in md5Buffer)
            {
                sb.Append(b.ToString("x2"));
            }
            md5.Clear();
            return sb.ToString();
        }
    }
}

使用:直接调用静态方法,传入string
