C# と VB.NET の質問掲示板

…んー、こゆことなのかな?

using System.Collections.Generic;

class Program {

  string[] strk1;
  string[] strk2;

  public void strSearchChar(string[] Char,string Find) {
    List<string> k1 = new List<string>();
    List<string> k2 = new List<string>();
    foreach ( string item in Char) {
      if( item.StartsWith(Find)) {
        k1.Add(item.Replace(Find,""));
      } else {
        k2.Add(item);
      }
    }
    strk1 = k1.ToArray();
    strk2 = k2.ToArray();
  }

  public void print() {
    foreach ( string item in strk1 ) {
      System.Console.Write("[{0}] ", item == null ? "NULL" : item);
    }
    System.Console.WriteLine();
    foreach ( string item in strk2 ) {
      System.Console.Write("<{0}> ", item == null ? "NULL" : item);
    }
  }

  public static void Main() {
    Program p = new Program();
    p.strSearchChar(new string[] { "aba", "abb", "acb", "aca", "ac" }, "ac" );
    p.print();
  }
}

ときにこんなテもある。
strk[0 .. pos-1] : strk1 相当
strk[pos .. Length-1] : strk2 相当

class Program {

  string[] strk;
  int pos;

  public void strSearchChar(string[] Char,string Find) {
    strk = new string[Char.Length];
    pos = 0;
    int rpos = Char.Length;
    foreach ( string item in Char) {
      if( item.StartsWith(Find)) {
        strk[pos++] = item.Replace(Find,"");
      } else {
        strk[--rpos] = item;
      }
    }
    System.Array.Reverse(strk, pos, strk.Length-pos);
  }

  public void print() {
    for ( int i = 0; i < pos; ++i ) {
      System.Console.Write("[{0}] ", strk[i]);
    }
    System.Console.WriteLine();
    for ( int i = pos; i < strk.Length; ++i ) {
      System.Console.Write("<{0}> ", strk[i]);
    }
  }

  public static void Main() {
    Program p = new Program();
    p.strSearchChar(new string[] { "aba", "abb", "acb", "aca", "ac" }, "ac" );
    p.print();
  }
}

質問ヘタ。
回答者に質問の意図を"伝え"にゃあかんでしょ。
"察してもらって"どうするよ!?
