我在 VB.NET 中有一个自定义用户控件的代码：

链接到代码

我使用此站点将其转换为 C#：

转换后的结果是：

using System.Windows.Forms;
using System.Drawing;
using System.ComponentModel;
public class TransparentLabel {

public TransparentLabel() {
    //  This call is required by the designer.
    InitializeComponent();
    //  Add any initialization after the InitializeComponent() call.
    //  Add any initialization after the InitializeComponent() call.
    this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
    this.SetStyle(ControlStyles.Opaque, true);
    this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
    this.components = new System.ComponentModel.Container();
    RF = new RectangleF(0, 0, base.Width, base.Height);
    LabelForeColorBrush = new SolidBrush(base.ForeColor);
}

private StringFormat sFormat;

private RectangleF RF;

private SolidBrush LabelForeColorBrush = null;

private void UpdateText() {
    try {
        sFormat = new StringFormat();
        int x = 0;
        int y = 0;
        // With...
        switch (TextAlignment) {
            case ContentAlignment.BottomCenter:

                sFormat.LineAlignment = StringAlignment.Near;
                break;
            case ContentAlignment.TopLeft:

                break;
        }
        sFormat.FormatFlags = StringDirection;
        ResizeControl();
    }
    catch (Exception ex) {
    }
}

private void ResizeControl() {
    RF.Size = new Size(base.Size);
    Invalidate();
}

private StringFormatFlags _StringDirection = (StringFormatFlags.NoClip < Description("The Direction of the Text."));

public StringFormatFlags StringDirection {
    get {
        return _StringDirection;
    }
    set {
        _StringDirection = value;
        UpdateText;
    }
}

private System.Drawing.ContentAlignment _TextAlignment = (ContentAlignment.MiddleCenter < Description("The Text Alignment that will appear on this control."));

public System.Drawing.ContentAlignment TextAlignment {
    get {
        return _TextAlignment;
    }
    set {
        _TextAlignment = value;
        UpdateText();
    }
}

public override System.Drawing.Color ForeColor {
    get {
        return base.ForeColor;
    }
    set {
        base.ForeColor = value;
        LabelForeColorBrush = new SolidBrush(value);
    }
}

private string _Labeltext = ("TransparentLabel" < Description("The text to be displayed in supports with real transparency."));

public string LabelText {
    get {
        return _Labeltext;
    }
    set {
        _Labeltext = value;
        Invalidate();
    }
}

[Browsable(false)]
[EditorBrowsable(false)]
public override System.Drawing.Color BackColor {
    get {
        return base.BackColor;
    }
    set {
        base.BackColor = value;
    }
}

protected override System.Windows.Forms.CreateParams CreateParams {
    get {
        CreateParams cp = base.CreateParams;
        cp.ExStyle = (cp.ExStyle | 32);
        return cp;
    }
}

protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) {
    try {
        base.OnPaint(e);
        //  draw the text on the control
        e.Graphics.DrawString(LabelText, base.Font, LabelForeColorBrush, RF, sFormat);
        //  MyBase.OnPaint(e)
    }
    catch (Exception ex) {
    }
}

private void TransparentLabel_Resize(object sender, System.EventArgs e) {
    ResizeControl();
}
}

但是这段代码有错误。其中一个是 ForInitializeComponent()和 for 基本关键字。我应该如何转换它？
