分隔符替换方法

本文关键字：方法 替换 分隔符 | 更新日期: 2023-09-27 18:02:31

我想创建一个方法来替换分隔符的预期目标用途(html电子邮件，日志，数据库)。分隔符是常量，所以我希望能够引用一个对象，将可识别的名称映射到字符串值(分号= ";"，htmlLineBreak = "
"等)。有没有比下面的方法更好的方法?

public static class Utilities
{
    public string ReplaceDelimiter(string content
                     , Delimiter currentDelimiter, Delimiter outputDelimiter)
    {
        return content.Replace(currentDelimiter.ToString()
                              , outputDelimiter.ToString());
    }
}
public class Delimiter
{
    public const string comma = ",";
    public const string semicolon = ";";
    public const string colon = ":";
    public const string lineBreak = "'r'n";
    public const string htmlLineBreak = "<br/>";
}

编辑以下注释:
一个用例是当我想记录一个错误到不同的目标，并在电子邮件中发送相同的内容(格式不同)。日志可以转到数据库列(希望键/值带有分号分隔符)或日志文件(希望分隔符为换行符)。电子邮件将是HTML，所以希望分隔符替换为
。

下面是一个日志方法的摘录，它有几个参数，包括实际的Exception:

StringBuilder delimitedMessage = new StringBuilder();
delimitedMessage.Append("Date=" + DateTime.Now.ToShortDateString() + ";");
delimitedMessage.Append("Time=" + DateTime.Now.ToLongTimeString() + ";");
delimitedMessage.Append("Source=" + objException.Source.ToString().Trim() + ";");
delimitedMessage.Append("Method=" + objException.TargetSite.Name.ToString() + ";");
delimitedMessage.Append("Erring Method=" + methodName + ";");
delimitedMessage.Append("Computer=" + System.Environment.MachineName.ToString() + ";");
delimitedMessage.Append("Log Message=" + logMessage + ";");
delimitedMessage.Append("Exception Error=" + objException.Message.ToString().Trim() + ";");
delimitedMessage.Append("Severity=" + severity.ToString() + ";");
delimitedMessage.Append("Stack Trace=" + objException.StackTrace.ToString().Trim() + ";");
contentToLog = delimitedMessage.ToString();
WriteToDb(contentToLog);
WriteToLog(Utilities.ReplaceDelimiter(contentToLog, Delimiter.semicolon, Delimiter.lineBreak));
SendEmail(Utilities.ReplaceDelimiter(contentToLog, Delimiter.semicolon, Delimiter.htmlLineBreak));

分隔符替换方法

  • 代码
    public class Delimiter {
    public static readonly Delimiter
        HtmlLineBreak=new Delimiter {
            Value="<br/>"
        },
        LineBreak=new Delimiter {
            Value="'r'n"
        },
        Semicolon=new Delimiter {
            Value=";"
        },
        Colon=new Delimiter {
            Value=":"
        },
        Comma=new Delimiter {
            Value=","
        };
    public override String ToString() {
        return Value;
    }
    public String Value {
        get;
        set;
    }
}
    • 测试

  • var t=Utilities.ReplaceDelimiter("123'r'n", Delimiter.LineBreak, Delimiter.HtmlLineBreak);
Debug.Print("{0}", t);

  • 输出

    123 & lt; br/祝辞
