Question

I had an adhoc insert statement created in c# code using string builder.

var str = new StringBuilder(string.Empty);
str.Append(" INSERT INTO Table_01 ( ID,");
        str.Append("Comment,");
        str.Append("DateTimeStamp,");
str.Append(" ) VALUES( ");
        str.Append("'" + Guid.NewGuid() + "',");
        str.Append("'" + CaseComment + "',");
        str.Append("CONVERT(DATETIME, '" + DateTime.Now.Year + "/" + DateTime.Now.Month + "/" + DateTime.Now.Day + "',120)");

I have converted this code to SqlParameter:-

var str = INSERT INTO Table_01(ID,Comment,DateTimeStamp)     
VALUES(@ID,@Comment,@DateTimeStamp)
using (var cmd = new SqlCommand(str, con))
{
cmd.Parameters.Add(new SqlParameter("@ID", Guid.NewGuid()));
cmd.Parameters.Add(new SqlParameter("@Comment", CaseComment));
cmd.Parameters.Add(new SqlParameter("@DateTimeStamp", ?????));
cmd.ExecuteNonQuery();
}

Before passing DateTime, I have to make sure that format is equal to “convert(varchar, getdate(), 120) — 2016-10-23 06:10:55(24h)” as in TSQL.
How will i pass @datetime parameter using TSQL Convert expression?

You can use Convert class. Try something like this,

cmd.Parameters.Add(new SqlParameter("@DateTimeStamp", Convert.ToDateTime(DateTime.Now)));

or

cmdItemSearch.Parameters.Add(new SqlParameter("@EndDate", SqlDbType.DateTime)); 
cmdItemSearch.Parameters["@EndDate"].Value = DateTime.Now;
