/* get the SPList object by list name*/
SPList lst = oSPWeb.Lists["EmpList"];
/* create a Numeric field for EmpID */
SPFieldNumber fldEmpID = (SPFieldNumber)lst.Fields.CreateNewField(
SPFieldType.Number.ToString(),
"EmpID");
        fldEmpID.Required =
true;
        fldEmpID.DisplayFormat =
SPNumberFormatTypes.NoDecimal;
/* create a Text field for Name */

SPFieldType.Text.ToString(),
"Name");
        fldName.Required =
true;
        fldName.MaxLength = 50;
/* create a Date field for Dob*/
SPFieldDateTime fldDob = (SPFieldDateTime)lst.Fields.CreateNewField(
SPFieldType.DateTime.ToString(),
"Dob");
        fldDob.DisplayFormat =
SPDateTimeFieldFormatType.DateOnly;
/* create a Currency field for Salary */
        SPFieldCurrency fldSal = (SPFieldCurrency)lst.Fields.CreateNewField(
SPFieldType.Currency.ToString(),

SPNumberFormatTypes.TwoDecimals;
/* add the new fields to the list */
        lst.Fields.Add(fldEmpID);
        lst.Fields.Add(fldName);
