Hashtable忽略大小写

在.net1.1中这样写

Hashtable htTemp  =   new  Hashtable(  new  CaseInsensitiveHashCodeProvider(),  new  CaseInsensitiveComparer() );

到了，.net2.0后提示过期

所以可以像下面这样写。

class  myCultureComparer : IEqualityComparer

    {

         #region  IEqualityComparer 成员

         public  CaseInsensitiveComparer myComparer;

         public  myCultureComparer()

        {

            myComparer  =  CaseInsensitiveComparer.DefaultInvariant;

        }

         public  myCultureComparer(CultureInfo myCulture)

        {

            myComparer  =   new  CaseInsensitiveComparer(myCulture); 

        }

         public   new   bool  Equals( object  x,  object  y)

        {

             if  (myComparer.Compare(x, y)  ==   0 )

            {

                 return   true ;

            }

             else

            {

                 return   false ;

            }

        }

         public   int  GetHashCode( object  obj)

        {

             return  obj.ToString().ToLower().GetHashCode();

        }

         #endregion

    }

使用的时候

Hashtable htTemp1  =   new  Hashtable( new  myCultureComparer());
