如何在asp.net中使用OR
问题描述:
我将提供以下内容
I will give the following
if((TXTBILLNO.Text = "") || (TXTBILLDATE.Text=""))
{
return(false);
}
但是错误显示在OR运算符上
错误是
运算符||不能应用于字符串类型为string
But the error is displayed on the OR operators
The error is
Operator || cannot be applied to operands of type string to strings
答
hi,
的操作数 你需要写''=='',
you need to write ''=='' ,
if((TXTBILLNO.Text == "") || (TXTBILLDATE.Text==""))
{
return(false);
}
希望这对您有用.
hopes this works for you.
