在vb.net中找到avarege [英] find avarege in vb.net

问题描述

如何将文本框值转换为整数.当我在文本框中输入值时，我需要获取平均值.我的代码是这样的
将nn变暗为double
nn = textbox1.text
将kk暗淡为double
kk = textbox2.文字
textb
kk = nn \ 4
然后我得到了错误的味精.它的`不能将字符串转换为double类型的值.
然后我尝试那样
将ll变暗为double
ll = textbox1.text
textbox2.text = ll \ 4
它的工作.
但是显示结果不是两倍
当我输入5到textbox1，然后单击按钮.结果是1.不是1.25
它不可能达到平均水平
请更正密码或为我提供帮助.
我正在使用vb.net
谢谢

推荐答案

您使用了错误的运算符.

\运算符返回除法的整数商.例如，表达式14 \ 4的值为3.
/运算符(Visual Basic)将完整的商(包括余数)返回为浮点数.例如，表达式14/4的计算结果为3.5.

参考: http://msdn.microsoft.com/en-us/library /se0w9esz(v=vs.80).aspx [ ^ ]

You are using wrong operator.

The \ Operator returns the integer quotient of a division. For example, the expression 14 \ 4 evaluates to 3.
The / Operator (Visual Basic) returns the full quotient, including the remainder, as a floating-point number. For example, the expression 14 / 4 evaluates to 3.5.

Ref:http://msdn.microsoft.com/en-us/library/se0w9esz(v=vs.80).aspx[^]

尝试kk=CDbl(nn)/4 .
您不应该得到该错误.

对于其他计算也要执行相同的操作.

Try kk=CDbl(nn)/4 .
You should not get the error.

Do the same thing for other calculations as well.
