私は解決する手がかりがない小さな問題があります。'string'を暗黙的に 'long'に変換できません。

public int FindByCPSA(string CPSA)
{
//set index to 0

//go through each record looking for CPSA number match
foreach (DataFileRecord dfr in DataFileRecords)
{
if (dfr.CPSA.ToLower() == CPSA.ToLower())
{
//if it's found return the current index
return index;
}
//increase index and move to next record
index++;

//return SingleString.Replace(",0", ""); //may be used to replace 0
//return SingleString.Replace(",", ", ");
}
私はこのコード行に問題がある
dfr.TotalSingleScore = s.Split(',')[12];
TotalSingleScoreがある:あなたがそのやっはものを見ることができるように、クラスからの電子コード;私は与えるだろう "エラー1暗黙的に 'string'型を 'long'に変換できません"
これを解決するにはどうすればよいですか? コードは、C#で、ソフトウェアは、VS 2008 Proの

これは、32ビットと64ビットのマシンで実行した場合とは異なる結果をもたらします。 Int64.parseがlongを返すInt64を明示的に使用しています。 int.Parse()!= long.Parse() –
もちろんです。私は彼の説明でintを読むだけです。 – Femaref
@Andrew、あなたは間違っています。 'int'は32ビットマシンであれ64ビットマシンであれ32ビットなので、結果は同じになります。 – svick
