this.toolStrip1 = new System.Windows.Forms.ToolStrip();
this.toolStrip1.Location = new System.Drawing.Point(0, 0);
this.toolStrip1.Name = "toolStrip1";
this.toolStrip1.Size = new System.Drawing.Size(444, 25);
this.toolStrip1.TabIndex = 0;
this.toolStrip1.Text = "toolStrip1";
object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

ToolStripButton btn = new ToolStripButton("m1");
btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
btn.Image = (Image)O;
this.toolStrip1.Items.Add(btn);

我建议:

System.Reflection.Assembly thisExe;
thisExe = System.Reflection.Assembly.GetExecutingAssembly();
System.IO.Stream file = 
    thisExe.GetManifestResourceStream("AssemblyName.ImageFile.jpg");
Image yourImage = Image.FromStream(file);

从msdn: http://msdn.microsoft.com/en-us/library/aa287676 (v = vs.71) . aspx

使用图像。FromStream更好，因为你不需要知道图像的格式(bmp, png，…)

或者你可以在处理WPF或Silverlight时使用这一行，特别是当你已经在XAML标记中有源字符串时:

(ImageSource)new ImageSourceConverter().ConvertFromString(ImagePath);

ImagePath是这样的:

string ImagePath  = "/ProjectName;component/Resource/ImageName.png";

最好的方法是将它们作为图像资源添加到项目的资源设置中。然后可以通过执行Resources.myimage直接获取映像。这将通过一个生成的c#属性获取图像。

如果你只是将图像设置为嵌入式资源，你可以通过:

string name = "Resources.myimage.jpg"
string namespaceName = "MyCompany.MyNamespace";
string resource = namespaceName + "." + name;
Type type = typeof(MyCompany.MyNamespace.MyTypeFromSameAssemblyAsResource);
Bitmap image = new Bitmap(type.Assembly.GetManifestResourceStream(resource));

其中mytypefrommsameassemblyasresource是程序集中的任何类型。

比大多数提议的答案简单多了

tslMode.Image = global::ProjectName.Properties.Resources.ImageName;

this.toolStrip1 = new System.Windows.Forms.ToolStrip();
this.toolStrip1.Location = new System.Drawing.Point(0, 0);
this.toolStrip1.Name = "toolStrip1";
this.toolStrip1.Size = new System.Drawing.Size(444, 25);
this.toolStrip1.TabIndex = 0;
this.toolStrip1.Text = "toolStrip1";
object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

ToolStripButton btn = new ToolStripButton("m1");
btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
btn.Image = (Image)O;
this.toolStrip1.Items.Add(btn);
