我需要执行通配符（ * ，？等）搜索的字符串。 这是我做了什么：

I need to perform Wildcard (*, ?, etc.) search on a string. This is what I have done:

string input = "Message";
string pattern = "d*";
Regex regex = new Regex(pattern, RegexOptions.IgnoreCase);

if (regex.IsMatch(input))
{
    MessageBox.Show("Found");
}
else
{
    MessageBox.Show("Not Found");
}

通过上面的code找到块击中，但实际上它不应该！

With the above code "Found" block is hitting but actually it should not!

如果我的模式是E *则只有发现应该打。

If my pattern is "e*" then only "Found" should hit.

我的理解或要求D *搜索应该查找包含后跟任意字符的文本D。

My understanding or requirement is d* search should find the text containing "d" followed by any characters.

我应该改变我的模式为D。*和e。*？是否有任何的.NET支持外卡同时使用正则表达式类，它内部是不是？

Should I change my pattern as "d.*" and "e.*"? Is there any support in .NET for Wild Card which internally does it while using Regex class?

推荐答案

这不是很难。从http://www.$c$cproject.com/KB/recipes/wildcardtoregex.aspx:

public static string WildcardToRegex(string pattern)
{
    return "^" + Regex.Escape(pattern)
                      .Replace(@"*", ".*")
                      .Replace(@"?", ".")
               + "$";
}

因此​​，像富的* .xls？将得到转化为 ^富。* 。xls的。$
