如何解决这个问题?请不要介意数据注释的文本，这只是为了测试。如何删除数据注释?

   [SuppressMessage("Microsoft.Globalization", "CA1303:Do not pass literals as localized parameters",
        MessageId = "YouSource.DI.Web.Areas.HelpPage.TextSample.#ctor(System.String)",
        Justification = "End users may choose to merge this string with existing localized resources.")]
    [SuppressMessage("Microsoft.Naming", "CA2204:Literals should be spelled correctly",
        MessageId = "bsonspec",
        Justification = "Part of a URI.")]
    public int Get1Number([FromBody]string name)

我有这个代码

    public void RemovePublicModifier()
    {
        this.method = this.SanitizeString(this.method, Public);
    }
    public void RemoveDataAnnotation()
    {
        int startIndex = this.method.LastIndexOf(']');
        var result = this.method.Substring(startIndex + 1).Trim();
        this.method = result;
    }
    private string SanitizeString(string method, string filter)
    {
        var items = method.Split(' ').ToList();
        var publicItem = items.Where(i => i == filter).FirstOrDefault();
        if (publicItem != null)
        {
            items.Remove(publicItem);
        }
        var result = string.Join(" ", items.ToArray()).Trim();
        return result;
    }

但是它给了我一个错误的结果。

       string name)

我想要的是。

      int Get1Number([FromBody]string name)

如何使用正则表达式删除特定字符

string inputStr = @"[SuppressMessage(""Microsoft.Globalization"", ""CA1303:Do not pass literals as localized parameters"",
MessageId = ""YouSource.DI.Web.Areas.HelpPage.TextSample.#ctor(System.String)"",
Justification = ""End users may choose to merge this string with existing localized resources."")]
[SuppressMessage(""Microsoft.Naming"", ""CA2204:Literals should be spelled correctly"",
MessageId = ""bsonspec"",
Justification = ""Part of a URI."")]
public int Get1Number([FromBody]string name)";
Console.WriteLine(Regex.Replace(inputStr, @"(^|'s*)'[['s'S]*?']'s*public's+", string.Empty));
public is also removed

试试这个

Regex.Replace(inputStr, @"(?<!'()'[[^']]+']'r'n", string.Empty));

它匹配包含在[]中的文本，但不匹配前面有(的文本

您可以尝试执行以下正则表达式替换:

(?ims)^'s*'[(?!'bpublic'b)['s'S]*?')']'s*public's*

用空字符串替换

c#: 

var result = Regex.Replace(str, @"(?ims)^'s*'[(?!'bpublic'b)['s'S]*?')']'s*public's*", string.Empty);

这是一个演示

尝试使用这个正则表达式，它将消除抑制消息，也支持其他访问修饰符:

('[[^]]+')'])(?<modifiers>'s+'w+'s)?

如果您不想删除访问修饰符，那么只需在Regex.Replace期间跳过此命名组。

演示

下面的代码将int Get1Number([FromBody]string name)提取到text变量。

var input = @" [SuppressMessage(""Microsoft.Globalization"", ""CA1303: Do not pass literals as localized parameters"",
        MessageId = ""YouSource.DI.Web.Areas.HelpPage.TextSample.#ctor(System.String)"",
        Justification = ""End users may choose to merge this string with existing localized resources."")]
    [SuppressMessage(""Microsoft.Naming"", ""CA2204:Literals should be spelled correctly"",
        MessageId = ""bsonspec"",
        Justification = ""Part of a URI."")]
        public int Get1Number([FromBody]string name)";
var match = Regex.Match(input, @"'w+'s+'w+'('[FromBody']'w+'s+'w+')");
var text = match.Groups[0].Value;
