提问by user1899761
I am getting this bug, I wrote code like this below
我遇到了这个错误，我在下面写了这样的代码
code:
代码：
decimal Amnt;
decimal.TryParse(txtAmnt.Text, out Amnt);
int tnure=1;
int.TryParse(txtTnre.Text, out tnure);
txtDdctAmnt.Text = (Amnt /tnure).ToString("0.00");
when in textbox value 0 I am getting this error.If it is possible give answer to me.
当文本框值为 0 时，我收到此错误。如果可能，请给我答案。

How about simply using an ifto check before dividing by zero?
if在除以零之前简单地使用一个来检查怎么样？
if(tnure != 0)
txtDdctAmnt.Text = (Amnt / tnure).ToString("0.00");
else
txtDdctAmnt.Text = "Invalid value";

check if tnureis not 0,you are getting Divide by Zero Exception,more help at http://msdn.microsoft.com/en-us/library/ms173160.aspx
检查是否tnure不为 0，您将得到除以零异常，更多帮助请访问http://msdn.microsoft.com/en-us/library/ms173160.aspx
decimal Amnt;
decimal.TryParse(txtAmnt.Text, out Amnt);
int tnure=1;
int.TryParse(txtTnre.Text, out tnure);
if(tnure!=0)
{
txtDdctAmnt.Text = (Amnt /tnure).ToString("0.00");
}
else
{
/*handle condition*/
}

Put your code in try/Catch Statement like this
像这样把你的代码放在 try/Catch 语句中
try
{
decimal Amnt;
decimal.TryParse(txtAmnt.Text, out Amnt);
int tnure=1;
int.TryParse(txtTnre.Text, out tnure);
txtDdctAmnt.Text = (Amnt /tnure).ToString("0.00");
}
catch(Exception ex)
{
// handle exception here
Response.Write("Could not divide any number by 0");
}

When tnre is 0, Amnt /tnureis a division by 0. You need to check whether tnre is 0 before dividing, and don't divide by tnre if it is equal to 0.
当tnre为0时，Amnt /tnure是除以0。除法前需要检查tnre是否为0，如果等于0就不要除以tnre。
