        {
            string readFile = @"C:\Log\*.txt";
            string writeFile = @"D:\DataLocate_PR_id.csv";
            Creating_CSV_File(readFile, writeFile);
        }

        private static void Creating_CSV_File(string readFrom, string writeTo)
        {
            try
            {
                StringBuilder sb = new StringBuilder();
                using (StreamReader sr = new StreamReader(readFrom))
                {
                    string delimiter = ";";
                    string line;
                    while ((line = sr.ReadLine()) != null)
                    {
                        string[] columns = line.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
                        sb.AppendLine(string.Join(delimiter, columns));
                    }
                }
                File.WriteAllText(writeTo, sb.ToString());
            }
            catch(Exception ex)
                {
                Console.WriteLine(ex.Message);
                Console.ReadLine();
                }
            }

What I have tried:

Current code getting error(Illegal characters in path), this is because I give * to read all .txt, but its need specific .txt file only, but I want it to read all .txt files.

if you want to read all .txt file, then read it separately using Directory class object and then read file one by one
see trailing code

C#

string[] array2 = Directory.GetFiles(@"C:\", "*.txt");

	// get all files and read them one by one.
	foreach (string name in array1)
	{
	    //your 'Creating_CSV_File' function goes here
	}
