推荐答案

数组应该像这样声明.. <在$ for循环中，你有硬编码的0值，它应该是数组长度..

array should be declared like this..

in the for loop you have hardcoded 0 value, it should be array length..

string[ ] aryText = "<1>,<2>,<3>,<4>,<5>,<6>";       
 string[] aryText= { "<1>","<2>","<3>","<4>","<5>","<6>"};

    System.IO.StreamWriter objWriter = new System.IO.StreamWriter(FILE_NAME, false);
    for (i = 0; (i <= 0); i++)
for (i = 0; (i <= aryText.Length); i++)
{
objWriter.WriteLine(aryText[i]);
