このファイルには、改行とがらくたデータのロードが含まれています。データベースにロードする前に、基本的に次のことを行う必要があります。ファイルを読み込んでテキスト ファイルの値を処理し、新しいファイルを出力する必要があります。

上を見ると、行：

"1","301897","N/A","Brother DR7000 Drum","Brother DR7000 Drum",,"Brother Drum","Brother DR7000 Drum",,,"301897-brother-drum"
"2","300021","N/A","Post-It Index Arrows 12mm 684-ARR4","Post It Index Arrows 12mm 684 ARR4",,"Post It Index Arrows ","Post-It Index Arrows 12mm 684-ARR4",,,"300021-post-it-index-arrows"

は正しい。

ただし、次の行：

"8558","SMP26","N/A","Shoreline SMP26 Portable Pharmacy Refrigerator","Shoreline SMP26 Portable Pharmacy Refrigerator",,,"Shoreline SMP26 Portable Pharmacy Refrigerator","·         12 Volt DC (fitted with Car cigarette lighter connection for mobile operation) or 220/110 Volt AC (fitted with 3 pin plug for mains power operation)

壊れているもの、

"(数値) が表示されたらファイルに新しい行を作成し、それ以外の場合は前の行に追加するというコードを少し書く必要があります。

Web フォーム アプリまたはコンソール アプリを作成する必要がありますが、それは問題ではありません。

必要なのは、引用符で囲まれた文字列をサポートする適切な CSV パーサーです。この質問には答えがあるかもしれません... Parsing CSV files in C#, with header .

本当に外部コードを使用できない場合は、コメントで提供した次の修正版のコードを試してください。

StreamReader reader = new StreamReader("input.txt");
List<string> result = new List<string>();
string new_line = reader.ReadLine();
string full_line = null;
while (new_line != null)
{
    // concatenate input when full_line not complete
    full_line = (full_line == null) ? new_line : full_line + new_line;
    // check for expected line completion pattern
    // looking for a " that is not escaped \" ... adapt this to your input assumptions
    if (new_line.EndsWith("\"") && !new_line.EndsWith("\\\""))
    {
        result.Add(full_line);
        full_line = null;
    }
    new_line = reader.ReadLine();
} 
reader.Close();

はい、皆さん、うまくいったと思います。ありがとうございました

StreamReader reader = new StreamReader(@"C:\test.txt");
StreamWriter writer = new StreamWriter(@"C:\test2.txt", true);

List<string> result = new List<string>();
string new_line = reader.ReadLine();
string full_line = null;

while (new_line != null)
{
    full_line = (full_line == null) ? new_line : full_line + new_line;

    if (new_line.EndsWith("\"") && !new_line.EndsWith("\\\""))
    {
        //Write to the List
        result.Add(full_line);
        //Reset the whole line
        full_line = null;
    }

    //Read the next line
    new_line = reader.ReadLine();
}

//Close the connection
reader.Close();

foreach (string readResult in result)
    writer.WriteLine(readResult);

ありがとうございました
