While passing data parameter from application getting exception.

2011-01-01 12:17:51.967

to do this I have written: 

client Application:

string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff",CultureInfo.InvariantCulture); 

PropertyClass prp=new PropertyClass();

Prp.TransDate=date; 

webserviceobj.CreateTansaction(Prp);

PropertyClass structure in webservice class:

Public class property

{

private string transdate; 

public string TransDate

    {

      get

      {

        return transdate;

      }

      set

      {

        transdate = value;

      }

    }

}

In webservice,From DAL layer passing the TransactionDate like this: 

Cmd.Parameters.Add("@TranSactionDate", SqlDbType.VarChar, 20).Value = propertyobj.TransDate; 

While debugging from client application: 

I am getting this exceptions: 

System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. at System.Data.SqlTypes.SqlDateTime.FromTimeSpan(TimeSpan value) at System.Data.SqlTypes.SqlDateTime.FromDateTime(DateTime value) at System.Data.SqlTypes.SqlDateTime..ctor(DateTime value) at System.Data.SqlClient.MetaType.FromDateTime(DateTime dateTime, Byte cb) at System.Data.SqlClient.TdsParser.WriteValue(Object value, MetaType type, Byte scale, Int32 actualLength, Int32 encodingByteSize, Int32 offset, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc) 

Note: my backend sql datefield wants the date paramter 2011-01-01 12:17:51.967 in this format, so I am passing this date as string. 

How can I solve this issue any help pls……. Your help is heartly appreciated.

Thanks,
