在C#中将字符串转换为十进制

问题描述

我在使用decimal.parse将字符串转换为十进制值时遇到一些问题.这是我的代码行:

I am having some problems converting string to decimal values with decimal.parse.This is the line of code I have:

fixPrice = decimal.Parse(mItemParts.Groups["price"].Value.Replace("$", "").Replace(" ", "").Replace("usd", ""));

我要转换的值是:'$ 779.99'

The value from which I am trying to convert is: '$779.99'

然后，一旦解析为十进制，我得到的值是:77999.

Then once the parsing to decimal happens, I am getting this value: 77999.

我希望获得779.99，而不是77999.在此先感谢Laziale

I would like to get 779.99 instead of 77999.Thanks in advance, Laziale

包含的正则表达式:"@" \ [^ \"] +?)\" [[^〜] +?\] +?src = \"((?[^ \"] +?)\""[^>] +?title = \"(?[^^"] +?)\""[^〜] +?price \">(?[^ \<] +?)\< [^〜] +?\(?[^ \<] +?)\

Regex included: "@"\[^\""]+?)\""[^~]+?\]+?src=\""(?[^\""]+?)\""[^>]+?title=\""(?[^\""]+?)\""[^~]+?price\"">(?[^\<]+?)\<[^~]+?\(?[^\<]+?)\

推荐答案

我会使用 Decimal.TryParse() :

decimal parsedDecimal = 0;
string yourCurrency = "$779.99";
bool didParse = Decimal.TryParse(yourCurrency,
                                 NumberStyles.Currency,
                                 new CultureInfo("en-US"), out parsedDecimal);

if(didParse) {
    // Parse succeeded
}
else {
    // Parse failed
}
