C: How to get the number of information in the txt file?

textreader reader;

int linecount = 0;

Method 1: while( = null) )length;

I haven't tested it, method 1 should be fine, method 2 can be imprecise, there is an error of 1.

Method 1 is to read each line honestly.

The idea of method 2, 3, and 4 is to count the number of occurrences of line breaks (), which is not very accurate. Because line breaks do vary from system to system. And your file is required to be very regular, and no blank lines are allowed.

You can define a variable int linecont=0; while (read by line until end)."Shared"+"OK");It's been a long time since I've written a program, I hope it helps you This answer is made by.

Damn, your method is really complicated, use mine! You can just copy the past call, and filepath refers to the file path public int getrows(string filepath)}

You should first see what format this txt is, I think this format is likely to be the format of csv, after determining the format, you can use the split method to divide it into an array, and then read it, if there is really no format, you can only use keyword positioning + regular expressions to achieve.

Instantiate a fileinfo object with a filepath, and the length property is the size (in bytes).

As for how many pieces of data, I don't understand what you want to say, if it's to check the number of rows in txt, use using (streamreader sr = fileinfo object. opentext())

It should be fine.

file class has, you can check it, and if you can't find it, look for me.

Isn't this an ini config file?

using system;

using ;

using ;

using ;

namespace ini

Read the ini file.

Node name.

ini file path.

Value. static public string inireadvalue(string section, string key, string filepath)}}

The format of your deposit is too messy, and it's so convenient to add start and end tags.

It is recommended to learn XML, which is the best for information saving.

Refer to the operation of the ini file.

I remember there were functions that read line by line, put them in an array of string str, and then go to the array and look for the contain element.
