Using Xamarin, how do I store data on a .csv file to local android storage?

Question

例如，如果我有两个数组ArrayX和ArrayY中的数据，如何将数据写入本地android存储中的.csv文件中？

Answer 1

this assumes ArrayX & ArrayY are non-null and have the same number of elements

string path = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "myfile.csv");

using (StreamWriter sw = File.CreateText(path))
{
    for (int ndx = 0; ndx <= ArrayX.Length; ndx++)
    {
      sw.WriteLine(ArrayX[ndx] + "," + ArrayY[ndx]);
    }
}
