İşlem zamanı görüntüleme

Burada yaptığım linq tekniği ile işlem zamanında çalışan programların ismini hafızada ne kadar yer kapladığını ve id sini vermek.

class ProcessData
{
  public Int32 Id;
  public Int64 Memory;
  String Name;
}

static void DisplayProcesses()
{
    List<ProcessData> processes = new List<ProcessData>();
    foreach (Process process in Process.GetProcesses())
    {
 ProcessData data = new ProcessData();
 data.Id = process.Id;
 data.Name = process.ProcessName;
 data.Memory = process.WorkingSet64;
 processes.Add(data);
    }
    processes.Dump();
}


static void Main()

Datatable ve çift dizili matris örneği

Datatable dan dönen değerleri çift dizili matrise çeviren method örneği.     

private static string[][] ConvertToArray(DataTable veri, int dizi)
        {
            string[][] veriler = new string[veri.Rows.Count][];

            int k = 0;
            foreach (DataRow r in veri.Rows)
            {
                veriler[k] = new string[dizi];

                for (int j = 0; j < veri.Columns.Count; j++)
                {
                    veriler[k][j] = ToolKit.ToString(r[j]);
                }
                k++;
            }
            return veriler;
        }

String.RemoveMany (Extension Method)

public static string RemoveMany(this string dirtyString, params string[] stringsToRemove)
{
            return dirtyString.Split(stringsToRemove, StringSplitOptions.None)
           .Aggregate((sentence, next) => sentence + next)

}

Kullanımı:
string dirty = "This is ABCa st)r(ing.";
string dirty2 = "tDEFes.t-";
string[] delims = new string[] { "ABC", "(", ")" };
Console.WriteLine(dirty.RemoveMany(delims));
Console.WriteLine(dirty2.RemoveMany("DEF", ".", "-"));
//output
"This is a string."
"test"

                   orderby row.Field<string>("ServerName"), row.Field<string>("InstanceName")
                   select string.Concat(
                        row.Field<string>("ServerName"),
                        row.Field<string>("InstanceName") != string.Empty
                            ? string.Concat("\\", row.Field<string>("InstanceName"))
                            : string.Empty);
        }
