如何不区分大小写？？
Hashtable ht = new Hashtable();

ht[ "Name "] = "yuna ";
ht[ "Pass "] = "123456 ";

if(ht.ContainsKey( "name "))
{
Response.Write(ht[ "name "].ToString());
}

// 只要是name 不管大小写都能输出，怎么做到？？


[解决办法]
明显不严谨。。这么做有什么好处呢？
[解决办法]
存进去的时候都小写或大写
读取的时候转换成小写或大写

Hashtable ht = new Hashtable();

ht[ "Name ".ToLower()] = "yuna ";
ht[ "Pass ".ToLower()] = "123456 ";

if(ht.ContainsKey( "name "))
{
Response.Write(ht[ "name "].ToString());
}
