VB.NET最新版本是哪个?
截至今天2016/12/02vb.net10,VB.net最新版本是VB 14vb.net10,
对应vb.net10的IDE为Visual Studio 2015
从VB 7开始vb.net10,每次.net平台更新,VB版本也会不断更新。
VB历史版本如下(.net平台)
没有 VB13
VB12 对应 VS2013
VB11 对应 VS2012
VB10 对应 VS2010
VB9 对应 VS2008
VB8 对应 VS2005
VB7 对应 VS2003
VB6 是经典版本,它不是 .net平台vb.net10的
相关问答
Q1: vb.net中十进制整数型表示范围
没有“十进制整数型表示范围”的说法,是整型或长整型类型的表示范围,每种数值类型都有常数,如Integer的最大值和最小值:Integer.MaxValue ,Integer.MinValue 。鼠标停留在这个语句上时会显示它的数值的。integer是32位的,大概有个20亿的正负值吧。
Q2: vb.net随机生成10个小于100的素数
listint SuNo = new listint();
//C#自带随机生成
Random rd = new Random();
for(int j = 0; j 99999; j++)
{
int i = rd.Next(1,100);
//拿到随机数后,下面做判断 i 是不是素数
.... //判断代码
if(是素数 SuNo.lengh = 10) //如果是素数并且集合数在10以内就把新的素数添加进去
{
SuNo.Add(i)
}
else
{
MessageBox.show("素数集合已达十个")
break;
}
}
//SuNo就是你要的集合,以后怎么处理看你的需求了
//=================手打可能会有些小问题我没测试过,素数是什么原谅我忘了,判断素数的方法你加进去就OK了
Q3: vb.net 1
1左移10位,1后面加10个0
结果就是:10000000000
五、按位运算符
注意不能在VB.Net中直接使用以下二进制数,使用时需转换为相应的十六或十进制数字。
1. 表示按位左移,空缺处补0。如:101101 2 结果为 110100
2. 表示按位右移,如:101101 2 结果为 001011
