将事件合并到一个处理程序中,效率如何?

这个问题有两个部分。

1. 每个对象有一个特定于事件的函数,还是合并对象事件更好?如果是这样,

我的事件功能:

private void GeneralEventHandler(object sender, EventArgs e){
        var senderHash = sender.GetHashCode();

        if (senderHash == tbDatabase.GetHashCode())
            Settings.DB.Default.Database = tbDatabase.Text;
        else if (senderHash == tbSchema.GetHashCode())
            Settings.DB.Default.Schema = tbSchema.Text;
}

我的对象定义:

    // tbDatabase
    / 
    this.tbDatabase.Anchor = ((System.Windows.Forms.AnchorStyles)((System.Windows.Forms.AnchorStyles.Left | System.Windows.Forms.AnchorStyles.Right)));
    this.tbDatabase.Location = new System.Drawing.Point(62, 3);
    this.tbDatabase.Name = "tbDatabase";
    this.tbDatabase.Size = new System.Drawing.Size(210, 20);
    this.tbDatabase.TabIndex = 0;
    this.tbDatabase.LostFocus += new System.EventHandler(this.GeneralEventHandler);
    // 
    // tbSchema
    // 
    this.tbSchema.Location = new System.Drawing.Point(55, 3);
    this.tbSchema.Name = "tbSchema";
    this.tbSchema.Size = new System.Drawing.Size(217, 20);
    this.tbSchema.TabIndex = 1;
    this.tbSchema.LostFocus += new System.EventHandler(this.GeneralEventHandler);

我主要是用它来动态更新用户设置。我在退出时保存设置文件。
