Parameter Date Conversion

Question

am using C#, VS 2005 and SQL 2000

I have date conversion problem my SQL table having field as below

Fields:

My SQL query in C# is

string sql = "insert into companymast (cname, datefrom, dateto) values(@cname, @datefrom, @dateto)";

SqlCommand cmd = new SqlCommand(sql, con);
cmd.Parameters.Add("@cname",SqlDbType.Varchar(50)).Values = cname.text;
cmd.Parameters.Add("@datefrom",SqlDbType.Datetime).Values = maskedTextBox1.text;
cmd.Parameters.Add("@dateto",SqlDbType.Datetime).Values = maskedTextBox2.text;
cmd.ExecuteNonQuery();

But the above throw Error Like date non conversion string to date

I have to put date in dd/MM/yyyy format code, 103

so how do i do?

Help me out, please.

Answer 1

maskedBox1.text is a string. You're assigning that to a SqlParameter's data member, and it tries to convert whatever it receives to the data type you request.

A more solid solution would be to convert to DateTime explicitly, and pass the converted value to the SqlParameter. This way, you have more control over the conversion, and you'll see exactly where and why it goes wrong when it does. Example:

DateTime fromDate = DateTime.Parse(maskedTextBox1.text);
cmd.Parameters.Add("@datefrom",SqlDbType.Datetime).Values= fromDate;

For DateTime.Parse, see: http://msdn.microsoft.com/en-us/library/1k1skd40.aspx
