如何使用图片？

Question

在程序中要用到一些图片，具体该怎么做呢？

Answer 1

什么程序，web还是form，用来干什么，这个问题实在是不懂

Answer 2

form中，像把一些图片放到datagridview中的行标头，根据内容的不同来显示不同的图标，比如内容是“warning”的就显示感叹号

Answer 3

imagelist中加入你的图片，然后在你要使用图片的控件中将属性设置到当前的imagelist,选择一个index就可以了

Answer 4

//程序上下文...Graphics grfx = CreateGraphics();
Image image = image.FromFile("路径");
grfx.DrawImage(image,0,0);//程序上下文

Answer 5

可是，我看到人家这样用的  /// <summary>
        ///   返回此类使用的缓存 ResourceManager 实例。
        /// </summary>
        [global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]
        internal static global::System.Resources.ResourceManager ResourceManager {
            get {
                if (object.ReferenceEquals(resourceMan, null)) {
                    global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("TestDataGridViewRowStyle.Properties.Resources", typeof(Resources).Assembly);
                    resourceMan = temp;
                }
                return resourceMan;
            }
        }
        
        /// <summary>
        ///   为使用此强类型资源类的所有资源查找
        ///   重写当前线程的 CurrentUICulture 属性。
        /// </summary>
        [global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]
        internal static global::System.Globalization.CultureInfo Culture {
            get {
                return resourceCulture;
            }
            set {
                resourceCulture = value;
            }
        }
        
        internal static System.Drawing.Bitmap arrow {
            get {
                object obj = ResourceManager.GetObject("arrow", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap down {
            get {
                object obj = ResourceManager.GetObject("down", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap GradeA {
            get {
                object obj = ResourceManager.GetObject("GradeA", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap GradeB {
            get {
                object obj = ResourceManager.GetObject("GradeB", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap GradeC {
            get {
                object obj = ResourceManager.GetObject("GradeC", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap GradeD {
            get {
                object obj = ResourceManager.GetObject("GradeD", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap GradeF {
            get {
                object obj = ResourceManager.GetObject("GradeF", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap high {
            get {
                object obj = ResourceManager.GetObject("high", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap low {
            get {
                object obj = ResourceManager.GetObject("low", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }
        
        internal static System.Drawing.Bitmap up {
            get {
                object obj = ResourceManager.GetObject("up", resourceCulture);
                return ((System.Drawing.Bitmap)(obj));
            }
        }这里面的internal static System.Drawing.Bitmap arrow 之类的东西是自己手动添加的吗？还是自动生成的？

Answer 6

System.Drawing.Bitmap是GDI+封装的类
用到需要自己添加 不是自动生成的

Answer 7

为什么我把上面的代码添加进去后，提示
“类型“remoting.Properties.Resources”已经包含“ResourceManager”的定义”？
“类型“remoting.Properties.Resources”已经包含“Culture”的定义”？

Answer 8

Rectangle _Col= dataGridView1.GetCellDisplayRectangle(0, 0, true);
e.Graphics.DrawIcon(this.Icon, new Rectangle(0, _Col.Y, _Col.X, _Col.Height)); 
或
第一列用Image控件，设置图片
或
private void DataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (DataGridView1.Columns[e.ColumnIndex].Name.Equals("Image"))
    {
        string path = e.Value.ToString();
        e.Value = GetImage(path);
    }
} 
public System.Drawing.Image GetImage(string path)
{
    return System.Drawing.Image.FromFile(path);
}
