I have a text e.x like that: Today, is a good day. Tomorrow, will rain!

推荐答案

您可以使用字符串函数Replace删除以下字符:

Hi,

You can use string function Replace to remove these characters:

string str="Today, is a good day. Tomorrow, will rain!";
str = str.Replace(",", "");
str = str.Replace(".", "");
str = str.Replace("!", "");
str = str.Replace(" ", "");

我认为System.Text.RegularExpressions.Regex类的Replace 方法可以用于此目的

I think the Replace method of System.Text.RegularExpressions.Regex class can be used for this purpose

string text = "Today, is     a good day. Tomorrow, will rain!";
//Remove punctuation characters and spaces
string textSansPunctuationSpace = System.Text.RegularExpressions.Regex.Replace(text,@"\p{P}|\s+","", RegexOptions.CultureInvariant);
Console.WriteLine (replacedText);
//Output:
//TodayisagooddayTomorrowwillrain

解决方案6很好.可能会尝试跟随，

Solution 6 is good. It might try following,

static void Main(string[] args)
{
    string str = "Today, is a good day. Tomorrow, will rain!";
    var result = new String(str.Where(ch => !Char.IsPunctuation(ch) && !Char.IsWhiteSpace(ch)).ToArray());
    Console.WriteLine(result);
}
