Question

I have a text file that is coming is some predefined way.
I don’t have something like it’s xsd, but the pattern can be seen.

for example it looks something like this:

[MyFIRSTPARAGRAPH]
NUM1 NUM2 NUM3 NUM4 NUM5 NUM6 NUM7 NUM8 NUM9 NUM10 NUM11
1 1 0.000 0.000 0.000 0 1 1 0 0 ""
2 2 22.800 0.000 0.000 0 1 1 0 0 ""
3 3 45.600 0.000 0.000 0 1 1 0 0 ""
4 4 68.400 0.000 0.000 0 1 1 0 0 ""
5 5 91.200 0.000 0.000 0 1 1 0 0 ""
6 6 0.000 32.800 0.000 0 1 1 0 0 ""
7 7 22.800 32.800 0.000 0 1 1 0 0 ""
8 8 45.600 32.800 0.000 0 1 1 0 0 ""
9 9 68.400 32.800 0.000 0 1 1 0 0 ""
10 10 91.200 32.800 0.000 0 1 1 0 0 "" 

A lot paragraphs separated by space lines.

Any saggestion what it the best what to parse files like this and to extract the values from the text.

My very first guess would be to do something like this:

using(var reader = GetStreamReader())
{
    bool justReadATag = false;
    string line = string.Empty;

    while((line = reader.ReadLine()) != null)
    {
        if(IsTag(line)) 
        {
            // do some work with the paragraph tag
            justReadATag = true;
        }else{
            string[] parts = line.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
            if(justReadATag) 
            {
                // do some work with the column names
                justReadATag = false;    
            }else
            {
                // do some work with the cell values
            }
        }
    }
}
