I am saying its not an exact copy from the link you mentioned but yes the classification and the description of the data type is but that is hardly any problem because MSDN also states the same thing in the same manner.

This is not at all duplicate ... This is illegal Copied from some author article.

there is very big difference b/w duplicate and Illegal copied.
and that is the reason all of them have been removed.

hello and thank you for your good discussion.
The question I have is this. we say we can hold any data type in object data type. we can hold integers, string, char, decimal and many others. so why would we need other data types? why microsoft put all of those int, string, char, byte, single, and ... to .net library. there must be a reason and I will be happy if anyone could help me.
thank you

You can use code:
Using System.Data.SqlClient;
using System.Collections.Specialized;
using System.Text;

Here’s the code block for deleting multiple records

#region Multiple Delete
private void DeleteRecords(StringCollection sc)
SqlConnection conn = new SqlConnection(GetConnectionString());
StringBuilder sb = new StringBuilder(string.Empty);

foreach (string item in sc)
const string sqlStatement = "DELETE FROM Customers WHERE CustomerID";
sb.AppendFormat("{0}='{1}'; ",sqlStatement, item);
SqlCommand cmd = new SqlCommand(sb.ToString(), conn);
cmd.CommandType = CommandType.Text;
catch (System.Data.SqlClient.SqlException ex)
string msg = "Deletion Error:";
msg += ex.Message;
throw new Exception(msg);
