C＃-ASP.NET-将日历中的日期插入数据库

Question

I am trying to store the date from a calendar which the user has selected into a database. It seems to not being inserting it into the Access Database. The DB field data type is Date/Time and the variables are below. I know my Query works because the other information stores correctly.

DateTime dtUserDate;
dtUserDate = calenderUserDate.SelectedDate;

string myQuery = "INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, Date Joined)   VALUES ( '" + strName + "' , '" + strEmail + "' , '" + strAddress + "' , '" + strTown + "' , '" + strCounty + "' , '" + strPostCode + "' , '" + strCountry + "' , '" + strTeleNumber + "' , '" + dtUserDate+ "')";

Thanks

try with

INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, [Date Joined]) ....

Note that your table column Date Joined having space, use [Date Joined]

Use Parameters as below

string myQuery = "INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, [Date Joined])   VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?)";
using (var cmd = new OleDbCommand(myQuery, con))
{
    cmd.Parameters.AddWithValue("Name", strName);
    ....
    cmd.Parameters.AddWithValue("DateJoined", dtUserDate);
