Visual Studio 2010上的图像按钮

我尝试使用以下方法在Form.Designer.cs文件上设置图像: // // button1 // this.button1.Location = new System.Drawing.Point(73, 11); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(39, 34); this.button1.TabIndex = 10; this.button1.UseVisualStyleBackColor = true; this.button1.Image = Properties.Resources.close_project_img;当我进入[设计]视图时，出现错误消息:To prevent possible data loss before loading the designer, the following errors must be resolved: Projectitem unavailable.

I drag & dropped the button, then I click the Image Property, I select a png image from my resource file, but the property always remain empty and the button doesn't have image neither on the [Design] view or in the compiled program.I tried setting the image on the Form.Designer.cs file with: // // button1 // this.button1.Location = new System.Drawing.Point(73, 11); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(39, 34); this.button1.TabIndex = 10; this.button1.UseVisualStyleBackColor = true; this.button1.Image = Properties.Resources.close_project_img;And when I go to the [Design] View, I get the error :To prevent possible data loss before loading the designer, the following errors must be resolved: Projectitem unavailable.
