十进制。解析方法

Question

I just found a very weird Bug in my c# code,

so there is a next:

when i´m trying to cast a object{string} to decimal like this :

item.ValiaFundo = row.IsNull("PL_FUNDO") ? 0 : decimal.Parse(row["PL_FUNDO"].ToString());

with the value of row = "2488.1987", it returns me 2488.1987 as supposed, but for some users returned value is 24881987.

i fixed it changing a type of object my database return to object{decimal}, like this :

item.ValiaFundo = row.IsNull("PL_FUNDO") ? 0 : (decimal)row["PL_FUNDO"];

that casts a value well for any user, and i just want to understand why that bug happens? What cause it? Does anyone have some ideas?

PS: server and users regional settings is the same for both cases.

Answer 1

But, seems that data coming from server is already decimal in type.

It is a bad practice to go decimal --> string --> decimal.

As Jon Skeet pointed out (his answer disappeared) in some cultures comma is a decimal point. So when doing ToString() be careful about culture used.
