獲取圖像顯示在自定義ButtonImage控件c＃

Question

我是新來的c＃，我試圖創建一個ButtonImage控件。我已經設法讓大部分代碼運行，包括TextAlignment和圖像資源選擇，但圖像不會顯示。我已經嘗試添加TextImageRelation屬性以及ImageAlignment屬性不起作用 - 甚至不知道我是否已經正確地做了一切。我花了幾個小時搜索MSDN和互聯網，請幫忙，TNX。繼承人的代碼：

namespace ImageButton 
{ 
    //[System.ComponentModel.DefaultBindingProperty("ButtonText")] 
    public partial class ImageButton : UserControl 
    { 
     private String name = "btn1"; 
     private String btnText = "Button1"; 
     private TextImageRelation textImage = TextImageRelation.Overlay; 
     private ContentAlignment alignmentValue = ContentAlignment.MiddleRight; 
     private ContentAlignment imageAlignmentValue = ContentAlignment.MiddleLeft; 

     public ImageButton() 
     { 
      InitializeComponent(); 
     } 
     // 
     // Properties 
     // 
     [Description("Sets the Text Label"), 
     Category("Custom")] 
     public String ButtonText 
     { 
      get 
      { 
       return btnText; 
      } 
      set 
      { 
       btnText = value; 
       btn1.Text = btnText; 
      } 
     } 
     [Description("Sets the Button Image"), 
     Category("Custom")] 
     public Image Image 
     { 
      get; 
      set; 
     } 
     [Description("Specifies the relationship of text to Image."), 
     Category("Custom")] 
     public TextImageRelation TextImageRelation { 
      get{ 
       return textImage; 
      } 
      set{ 
       textImage =value; 
       btn1.TextImageRelation = textImage; 
      } 
     } 
     [Category("Custom"), 
     Description("Specifies the alignment of text.")] 
     public ContentAlignment TextAlignment 
     { 
      get 
      { 
       return alignmentValue; 
      } 
      set 
      { 
       alignmentValue = value; 
       btn1.TextAlign = alignmentValue; 
       //Invalidate(); 
      } 
     } 
     [Category("Custom"), 
     Description("Specifies the alignment of text.")] 
     public ContentAlignment ImageAlignment 
     { 
      get 
      { 
       return imageAlignmentValue; 
      } 
      set 
      { 
       imageAlignmentValue = value; 
       btn1.ImageAlign = imageAlignmentValue; 
      } 
     }  
     protected override void OnPaint(PaintEventArgs e) 
     { 
      base.OnPaint(e); 
      StringFormat style = new StringFormat(); 
      style.Alignment = StringAlignment.Far; 
      switch (alignmentValue) 
      { 
       case ContentAlignment.MiddleLeft: 
        style.Alignment = StringAlignment.Near; 
        break; 
       case ContentAlignment.MiddleRight: 
        style.Alignment = StringAlignment.Far; 
        break; 
       case ContentAlignment.MiddleCenter: 
        style.Alignment = StringAlignment.Center; 
        break; 
      } 
      // Call the DrawString method of the System.Drawing class to write 
      // text. Text and ClientRectangle are properties inherited from 
      // Control. 
      e.Graphics.DrawString(
       Text, 
       Font, 
       new SolidBrush(ForeColor), 
       ClientRectangle, style); 
     } 
    } 
}

解決：

代替：

public Image Image{ get; set;} 

其他PPL建議，我用

public Image Image{ 
     get { return image; } 
     set 
     { 
      image = value; 
      btn1.Image = image; 
     } 
    }
