好吧，每列似乎是一个固定的宽度，所以只需弄清楚每列的宽度，并为文件中的每个字符串做一个修剪（子串（行，x， y））其中x是要开始的字符串的索引，y是列的宽度。
不要忘记在第一行数据之前不解析任何内容，并处理行可能并不总是你预期的长度的可能性。
你需要意识到它看起来你不需要解析一个字符串。
如果你打开文件在Excel中你会注意到Excel将其识别为固定宽度文件;所以你需要的是一个文件解析器。
这里有很多例子。虽然这个是十年之久，但它仍然有效。

VB还有一个TextFieldParser类，如果您在Microsoft.VisualBasic.FileIO命名空间中添加引用，则可以使用该类/ BLOCKQUOTE>
I am having output in the following manner. I am trying to parse that output and assign it to a datatable but i am facing difficulty because the output column text have spaces between the character because of that i am unable to split data in equal columns

What I have tried:
I tried the following method:
string[] stringSeparators = new string[] {"\r\n"};
string[] lines = OutputFilePath.Split(stringSeparators, StringSplitOptions.RemoveEmptyEntries);
lines = lines.Where(x => !string.IsNullOrEmpty(x)).ToArray();
foreach (var item in lines.Skip(5))
{
//formatedop = item.Split(' ');
formatedop = Regex.Split(item, @"\s{1,}");
formatedop = formatedop.Where(x => !string.IsNullOrEmpty(x)).ToArray();
try
{
if (formatedop.Length > 16)
{
if (formatedop[1].Contains("(scheduled)"))
{
formatedop[0] = formatedop[0] + " " + formatedop[1];
formatedop[5] = formatedop[5] + " " + formatedop[6] + " " + formatedop[7];
table.Rows.Add(
formatedop[0].ToString(),
formatedop[2].ToString(),
formatedop[3].ToString(),
formatedop[4].ToString(),
formatedop[5].ToString(),
formatedop[8].ToString(),
formatedop[9].ToString(),
formatedop[10].ToString(),
formatedop[11].ToString(),
formatedop[12].ToString(),
formatedop[13].ToString(),
formatedop[14].ToString(),
formatedop[15].ToString(),
DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"));
}
if (formatedop[1].Contains("Oracle8"))
{
formatedop[1] = formatedop[1] + " " + formatedop[2];
formatedop[5] = formatedop[5] + " " + formatedop[6] + " " + formatedop[7];
table.Rows.Add(
formatedop[0].ToString(),
formatedop[1].ToString(),
formatedop[3].ToString(),
formatedop[4].ToString(),
formatedop[5].ToString(),
formatedop[8].ToString(),
formatedop[9].ToString(),
formatedop[10].ToString(),
formatedop[11].ToString(),
formatedop[12].ToString(),
formatedop[13].ToString(),
formatedop[14].ToString(),
formatedop[15].ToString(),
DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"));
}
}
else
{
formatedop[5] = formatedop[5] + " " + formatedop[6] + " " + formatedop[7];
table.Rows.Add(
formatedop[0].ToString(),
formatedop[1].ToString(),
formatedop[2].ToString(),
formatedop[3].ToString(),
formatedop[4].ToString(),
formatedop[5].ToString(),
formatedop[8].ToString(),
formatedop[9].ToString(),
formatedop[10].ToString(),
formatedop[11].ToString(),
formatedop[12].ToString(),
formatedop[13].ToString(),
formatedop[14].ToString(),
formatedop[15].ToString(),
DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"));
}
}
catch(System.Exception ex)
{
formatedop[0].ToString();
Console.WriteLine(ex.InnerException.ToString());
}
}
But this is not working properly. It breaks at one or the other line. I need a clean and clear method. Can anyone suggest something. I need output like this:
formatedop[0]=Backup
formatedop[1]=IDB IDB_Backup
formatedop[2]=Completed
formatedop[3]=full
formatedop[4]=10/10/2018 11:50:07
formatedop[5]=0:00
formatedop[6]=1:07
formatedop[7]=1345.11
formatedop[8]=1
formatedop[9]=0
formatedop[10]=0
formatedop[11]=23794
formatedop[12]=100%
formatedop[13]=2018/10/10-38
Well, each column appears to be a fixed width, so simply figure out how many characters wide each column is, and for each string in the file, do aTrim(Substring(line, x, y))where x is the index into the string to start in, and y is the width of the column.
Don't forget to NOT parse anything before the first line of data, and handle the possibility that the line may not always be the length you expect it to be.
You need to realize that it looks like you don't need to parse a string.
If you open the file up in Excel you will notice Excel recognizes this as a "Fixed-Width" file; so what you need is a file parser.
There are quite a few examples of this out there. While this one is one over a decade old it is still functional.

VB also has aTextFieldParserclass that can be used if you add in a referecne to theMicrosoft.VisualBasic.FileIOnamespace
