(.NET Core ではなく) .NET Framework を使用している場合は、System.Net.HttpRequestHeader列挙型を適切にフォーマットする拡張メソッドを作成できます。
using System;
using System.Net;
using System.Text;
namespace YourNamespace
{
public static class HttpRequestHeaderEx
{
public static string ToStandardName(this HttpRequestHeader requestHeader)
{
string headerName = requestHeader.ToString();
var headerStandardNameBuilder = new StringBuilder();
headerStandardNameBuilder.Append(headerName[0]);
for (int index = 1; index < headerName.Length; index++)
{
char character = headerName[index];
if (char.IsUpper(character))
{
headerStandardNameBuilder.Append('-');
}
headerStandardNameBuilder.Append(character);
}
string headerStandardName = headerStandardNameBuilder.ToString();
return headerStandardName;
}
}
}
使用法：
var userAgentHeaderName = HttpRequestHeader.UserAgent.ToStandardName();
