[C#] CSVファイルを書き出す – 端くれプログラマの備忘録

CSVファイルへの書き出しは、書き出す項目をカンマで区切って連結する以外は、テキストファイルへの書き出しと変わらない。

// Word array.
string[] fields = { "apple", "orange", "lemon", "pineapple" };

// Joins the words with commas.
string outstr = string.Join(",", fields);

// Writing to the text file.
StreamWriter sw = new StreamWriter(@"C:\Temp\Text3.txt");
sw.WriteLine(outstr);
sw.Close();

// Text3.txt
// "apple,orange,lemon,pineapple"

// Word array.

string[] fields = { "apple", "orange", "lemon", "pineapple" };

// Joins the words with commas.

string outstr = string.Join(",", fields);

// Writing to the text file.

StreamWriter sw = new StreamWriter(@"C:\Temp\Text3.txt");

sw.WriteLine(outstr);

sw.Close();

// Text3.txt

// "apple,orange,lemon,pineapple"
