When you create a DataTable or DataSet, you should set the locale explicitly. By default, the locale for these types is
the current culture. For data that is stored in a database or file and is shared globally, the locale should ordinarily be set to the invariant
culture (CultureInfo.InvariantCulture).
This rule raises an issue when System.Data.DataTable or System.Data.DataSet instances are created without explicitly
setting the locale property (DataTable.Locale or DataSet.Locale).
Noncompliant code example
using System;
using System.Data;
namespace MyLibrary
{
public class Foo
{
public DataTable CreateTable()
{
DataTable table = new DataTable("Customers"); // Noncompliant table.Locale not set
DataColumn key = table.Columns.Add("ID", typeof(Int32));
key.AllowDBNull = false;
key.Unique = true;
table.Columns.Add("LastName", typeof(String));
table.Columns.Add("FirstName", typeof(String));
return table;
}
}
}
Compliant solution
using System;
using System.Data;
using System.Globalization;
namespace MyLibrary
{
public class Foo
{
public DataTable CreateTable()
{
DataTable table = new DataTable("Customers");
table.Locale = CultureInfo.InvariantCulture;
DataColumn key = table.Columns.Add("ID", typeof(Int32));
key.AllowDBNull = false;
key.Unique = true;
table.Columns.Add("LastName", typeof(String));
table.Columns.Add("FirstName", typeof(String));
return table;
}
}
}
