错误：字符串未被识别为有效的DateTime。

Question

错误：字符串未被识别为有效的DateTime。 以下是堆栈跟踪-

“位于System.DateTimeParse.Parse（String s，DateTimeFormatInfo dtfi，DateTimeStyles样式）\\ r \\ n位于System.Convert.ToDateTime（字符串值）\\ r \\ n位于ConsoleApplication10.Program.b_1 1（<> 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 C：\\ Documents and Settings \\ hj81dev \\ My Documents \\ Visual Studio 2008 \\ Projects \\ ConsoleApplication10 \\ ConsoleApplication10 \\ Program.cs：line 28 \\中的ConsoleApplication10.Program.Main（String [] args）处的.MoveNext（）\\ r \\ n r \\ n在System.AppDomain._nExecuteAssembly（Assembly assembly，String [] args）\\ r \\ n在System.AppDomain.ExecuteAssembly（String assemblyFile，Evidence assemblySecurity，String [] args）\\ r \\ n在Microsoft.VisualStudio.HostingProcess .HostProc.RunUsersAssembly（）\\ r \\ n在System.Threading.ThreadHelper.ThreadStart_Context（对象状态）\\ r \\ n在System.Threading.ExecutionContext.Run（ExecutionContext exe cutionContext，ContextCallback回调，对象状态）\\ r \\ n位于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;
            }
        }
    }

请只做那些需要的

设置cultureinfo以确保使用哪种格式

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