■ Action デリゲート
Actin
・T型の引数を1つ、戻り値なし(void)メソッドをとるデリゲート
構文
private Action<【引数の型】, ...> 【メソッドを格納する変数】 { get; set; } 【メソッドを格納する変数】 = 【メソッド名】
■ サンプル
private string Name { get; set; } private string Occupation { get; set; } private Action<string> Method { get; set; } private void button1_Click(object sender, EventArgs e) { this.Name = "Blank"; this.Occupation = "Blank"; // this.Method = new Action<string>(this.SetOccupation);と同じ this.Method = this.SetOccupation; this.Method("Programmer"); this.label1.Text = this.Name; this.label2.Text = this.Occupation; } private void SetName(string value) { this.Name = value; } private void SetOccupation(string value) { this.Occupation = value; }
出力結果
Blank Programmer
