计算字符串中的字符数 [英] Count the number of characters in a string
问题描述
大家好
使用Visual Studio C＃
有一个字符串
string st =这些椒盐脆饼让我口渴;喝这茶。
像heck一样跑。
******
我怎么去计算此字符串中的字符数
，不包括逗号，分号，空格和句点。
想在标签中显示数字结果。
如有任何建议，我们将不胜感激。

2个字：正则表达式。 :)
类似于以下内容：
匹配m = Regex.Match（st，[az] [AZ] [ 0-9]"）;
if（m.Match）
{
Debug.WriteLine（m.Length）;
}
（我没有测试代码，所以你可能必须使用正则表达式。）

bebop，
正则表达式可用于捕获字符串中
字母的数量：
使用System.Text.RegularExpressions;
....
string st ="这些椒盐脆饼让我口渴;喝这茶。像heck一样运行。;
this.Label1.Text = Regex.Matches（st，[a-zA-Z]"）。Count.ToString（）;

希望这会有所帮助。

请通过正则表达式会员，您将得到所需的一切。一个
的替代建议是如果你有一套你想忽略的字符
在计数期间，请在正则表达式中使用替换动词。
Hi all
Using Visual Studio C#
Have a string
string st = "Hi, these pretzels are making me thirsty; drink this tea.
Run like heck."
******
How would I go about counting the number of characters in this string
without including the commas, semicolons, spaces, and periods.
Would like to display the number result in a label.
Any suggestions would be appreciated.

2 words: Regular Expressions. :)
Something along the lines of:
Match m = Regex.Match(st, "[a-z][A-Z][0-9]");
if(m.Match)
{
Debug.WriteLine(m.Length);
}
(I didn''t test the code, so you may have to play with the regex expression.)

bebop,
A regular expression can be used to capture the number of
letters in the string:
using System.Text.RegularExpressions;
....
string st = "Hi, these pretzels are making me thirsty; drink this tea. Run like heck.";
this.Label1.Text = Regex.Matches(st, "[a-zA-Z]").Count.ToString();

Hope this helps.

Please go through Regex members, you will fine what you need. One
alternate suggestion is if you have set of charaters you want to ignore
during the count, use replace verb in the Regex.
