ウィンドウ位置・サイズを記憶する

プロジェクトのプロパティで次のように設定する。

復元

private void frmHome_Load(object sender, EventArgs e)
{
    //ウィンドウの位置、サイズを復元
    Bounds = Properties.Settings.Default.Bounds;
    WindowState = Properties.Settings.Default.WindowState;
}

保存

private void frmHome_FormClosing(object sender, FormClosingEventArgs e)
{
    //画面プロパティを保存する（BEGIN）
    if (WindowState == FormWindowState.Normal)
    {
        Properties.Settings.Default.Bounds = Bounds;
    }
    else
    {
        Properties.Settings.Default.Bounds = RestoreBounds;
    }

    Properties.Settings.Default.WindowState = WindowState;

    Properties.Settings.Default.Save();
    //画面プロパティを保存する（END）
}

C#での一般的なシングルトンの実装

C# singleton

staticコンストラクタを使用する。

public class MySingleton
{
    private static readonly MySingleton theOneAndOnly;

    static MySingleton()
    {
        theOneAndOnly = new MySingleton();
    }

    public static MySingleton TheOnly
    {
        get { return theOneAndOnly; }
    }

    private MySingleton()
    {
    }
}

標準的なSystem.Object.Equals()のオーバーライド実装

C# effective C#

public class Foo : IEquatable<Foo>
{
    public override bool Equals(object right)
    {
        //nullチェック
        if (Object.ReferenceEquals(right, null))
            return false;

        if (Object.ReferenceEquals(this, right))
            return true;

        if (this.GetType() != right.GetType())
            return false;

        return this.Equals(right as Foo);
    }

    #region IEquatable<Foo> メンバー
    public bool Equals(Foo other)
    {
        //省略
        return true;
    }
    #endregion

例外を発生させない
GetType()で型を比較する
IEquatableを実装する
親クラスがObjectまたはValueTypeでない場合は親クラスのEquals()を呼ぶ
GetHashCode()をオーバーライドする
値型の場合は、==演算子もオーバーライドする※参照型の場合は基本的に不要
