错误：字符串未被识别为有效的DateTime。下面是堆栈跟踪 -

“在System.DateTimeParse.Parse（String s，DateTimeFormatInfo dtfi， SystemTime上的DateTimeStyles样式）\ r \ n在System.Convert.ToDateTime（String 价值）\ r \ n at ConsoleApplication10.Program.b_ 1（＆lt;＆gt; f _AnonymousType0 1 a) in C:\\Documents and Settings\\xxxxdev\\My Documents\\Visual Studio 2008\\Projects\\ConsoleApplication10\\ConsoleApplication10\\Program.cs:line 23\r\n at System.Linq.Enumerable.WhereSelectListIterator 2.MoveNext（）\ r \ n at C：\ Documents和中的ConsoleApplication10.Program.Main（String [] args） Settings \ hj81dev \ My Documents \ Visual Studio 2008 \项目\ ConsoleApplication10 \ ConsoleApplication10 \的Program.cs：行 28 \ r \ n在System.AppDomain._nExecuteAssembly（程序集， System.AppDomain.ExecuteAssembly（String，String [] args）\ r \ n assemblyFile，Evidence assemblySecurity，String [] args）\ r \ n at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly（个）\ r \ n 在System.Threading.ThreadHelper.ThreadStart_Context（对象状态）\ r \ n 在System.Threading.ExecutionContext.Run（ExecutionContext executionContext，ContextCallback回调，对象状态）\ r \ n at System.Threading.ThreadHelper.ThreadStart（）“

这是我的代码。在sql server数据库中，我的dateofbirth字段是varbinary类型

class Program
    {
        static void Main(string[] args)
        {
            var customerProfileGuid = new Guid("35D02589-C5FA-437D-B661-000215C68584");
            using (CustomerProfileEntities context = new CustomerProfileEntities())
            {
                var test = from x in context.CustomerProfile
                           where x.CustomerProfileId == customerProfileGuid
                           select new { x };

                var customerData = test.ToList();
                var customerResult = (from a in customerData
                                      select new Profile
                                      {
                                          DateOfBirth =Convert.ToDateTime(Encoding.UTF8.GetString(a.x.DateOfBirth)) //getting error here
                                      });

                foreach (var profile in customerResult)
                {
                    var profileData = profile;
                }
            }

        }
    }
    public class Profile
    {
        private DateTime dateOfBirthField;

        [System.Xml.Serialization.XmlElementAttribute(DataType = "date")]
        public DateTime DateOfBirth
        {
            get
            {
                return this.dateOfBirthField;
            }
            set
            {
                this.dateOfBirthField = value;
            }
        }
    }

请做必要的

var cultureInfo = new CultureInfo(yourCulture);
Thread.CurrentThread.CurrentCulture = cultureInfo;
