先感谢您!我正在编写一个应用程序来读取txt文件并写入Excel.从小做起我只是想读第一行.

Console.WriteLine正确输出字符串(字符之间有空格),但是当我尝试从字符串中提取字符时,我收到此错误:附加信息:索引和长度必须引用字符串中的位置.

while ((input = stream.ReadLine()) != null)
{
  //ACH HEADER LINE
  if (iCurRecLine == 0 && input.IndexOf(HeaderBeginKeyWord) >= 0)     
  {
    Console.WriteLine(input);

    RepDate = input.Substring(23, 6).Trim();
    RecordTypeCode = input.Substring(0, 1).Trim();
    PriorityCode = input.Substring(1, 2).Trim();
    ImmDestination = input.Substring(3, 10).Trim();
    ImmOrigin = input.Substring(13, 10).Trim();
    FileCreatedDate = input.Substring(23, 6).Trim();
    FileCreatedTime = input.Substring(29, 4).Trim();
    FileIDModifier = input.Substring(33, 1).Trim();
    RecordSize = input.Substring(34, 3).Trim();
    BlockingFactor = input.Substring(37, 2).Trim();
    FormatCode = input.Substring(39, 1).Trim();
    Destination = input.Substring(40, 23).Trim();
    Origin = input.Substring(63, 23).Trim();
    ReferenceCode = input.Substring(86, 8).Trim();
    ...
  } …
