DJ Kraze のアプローチをお勧めします: カスタム リストを作成し、それを DataGridView にバインドします。カスタムコードを使用して行を解析するだけです。必要に応じて DataTable を使用することもできますが、通常は List アプローチの方がクリーンです。
次のようなものです(正確な構文やメソッド呼び出しを確認していないため、例としてのみ使用してください。たとえば、テキストリーダーが必要になります):
public class LogEntry {
public string Description { get; set; }
public DateTime LogDate { get; set; }
// other properties you want to extract
}
public class LogReader {
public List<LogEntry> ReadLog(string fileName){
var parsedLog = new List<LogEntry>();
using(var file = File.Open(filename, ....)){
while(var line = file.ReadLine()){
var logEntry = ParseLine(line);
parsedLog.Add(logEntry);
}
}
return parsedLog;
}
private LogEntry ParseLine(string line){
var logEntry = new LogEntry();
// go through the line and parse it with string functions and populate values.
// I use a helper class, a shortened version is below - note, you might need to
//adjust to compile
var parser = new StringParser(line);
//now just use GetBetween to find the values you need. just pick your delimiters
// carefully as the parser will move beyond the end string. But it will go
// sequentially so just experiment
logEntry.Description = parser.GetBetween("LOG[", "]LOG");
// go through in order
}
}
public class StringParser {
private string text;
private int position;
public StringParser(string text)
{
this.Text = text;
}

{
this.text = value;

}
}

{

{

{
this.position = 0;
}

this.position = value > this.Text.Length ? this.Text.Length : value;

{
