为所有找到Lucene的人。Net作为一个多余的删除变音符，我设法找到这个小库，利用ASCII音译为您。

在这里弹出这个库，如果您还没有考虑过的话。看起来有一个完整的单元测试。

你可以从MMLib中使用字符串扩展。扩展nuget包:

using MMLib.RapidPrototyping.Generators;
public void ExtensionsExample()
{
  string target = "aácčeéií";
  Assert.AreEqual("aacceeii", target.RemoveDiacritics());
} 

Nuget页面:https://www.nuget.org/packages/MMLib.Extensions/ Codeplex项目网站https://mmlib.codeplex.com/

这就是我如何在所有的。net程序中替换变音符字符为非变音符字符

C#:

//Transforms the culture of a letter to its equivalent representation in the 0-127 ascii table, such as the letter 'é' is substituted by an 'e'
public string RemoveDiacritics(string s)
{
    string normalizedString = null;
    StringBuilder stringBuilder = new StringBuilder();
    normalizedString = s.Normalize(NormalizationForm.FormD);
    int i = 0;
    char c = '\0';

    for (i = 0; i <= normalizedString.Length - 1; i++)
    {
        c = normalizedString[i];
        if (CharUnicodeInfo.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)
        {
            stringBuilder.Append(c);
        }
    }

    return stringBuilder.ToString().ToLower();
}

VB .NET:

'Transforms the culture of a letter to its equivalent representation in the 0-127 ascii table, such as the letter "é" is substituted by an "e"'
Public Function RemoveDiacritics(ByVal s As String) As String
    Dim normalizedString As String
    Dim stringBuilder As New StringBuilder
    normalizedString = s.Normalize(NormalizationForm.FormD)
    Dim i As Integer
    Dim c As Char

    For i = 0 To normalizedString.Length - 1
        c = normalizedString(i)
        If CharUnicodeInfo.GetUnicodeCategory(c) <> UnicodeCategory.NonSpacingMark Then
            stringBuilder.Append(c)
        End If
    Next
    Return stringBuilder.ToString().ToLower()
End Function

试试helppersharp包。

有一个方法removeaccent:

 public static string RemoveAccents(this string source)
 {
     //8 bit characters 
     byte[] b = Encoding.GetEncoding(1251).GetBytes(source);

     // 7 bit characters
     string t = Encoding.ASCII.GetString(b);
     Regex re = new Regex("[^a-zA-Z0-9]=-_/");
     string c = re.Replace(t, " ");
     return c;
 }

这是VB版本(工作与希腊):

导入系统。文本

导入系统。全球化

Public Function RemoveDiacritics(ByVal s As String)
    Dim normalizedString As String
    Dim stringBuilder As New StringBuilder
    normalizedString = s.Normalize(NormalizationForm.FormD)
    Dim i As Integer
    Dim c As Char
    For i = 0 To normalizedString.Length - 1
        c = normalizedString(i)
        If CharUnicodeInfo.GetUnicodeCategory(c) <> UnicodeCategory.NonSpacingMark Then
            stringBuilder.Append(c)
        End If
    Next
    Return stringBuilder.ToString()
End Function
