public string[] ToArray
ArrayList list = new ArrayList();
list.Add( "aaa" );
list.Add( "bbb" );
string[] arrString = (string[])list.ToArray( typeof( string ) ) ;
方法2: ArrayList 与 string[] 的转换
======================================
ArrayList list = new ArrayList();
list.Add( "aaa" );
list.Add( "bbb" );
string[] arrString = new string[list.Count];
for( int i = 0 ; i < list.Count ; i ++ ){
arrString[i] = list[i].ToString();
}
方法3: 将string转换成ArrayList类型
===========================================
string str="1,2,3,4,5";
ArrayList b = new ArrayList( str.Split(',') ) ;
