Question

我必须创建一个窗口表单，将MySQL表绑定到DataGridView，我的DataGridView看起来像这样

func (b *Buffer) Read(p []byte) (n int, err error)

func (sh serverHandler) ServeHTTP(rw ResponseWriter, req *Request)

func (r Rectangle) Size() Point

使用此代码

ID     Name      PIC
1      Leo       64BaseStringImage
2      hello     64BaseStringImage

是否可以使DataGridView成为这个？

mcon.Open();
MySqlDataAdapter MyDA = new MySqlDataAdapter();
string sqlSelectAll = "SELECT id,name,pic from stockitem ORDER BY id ASC, name ASC";
MyDA.SelectCommand = new MySqlCommand(sqlSelectAll, mcon);

DataTable table = new DataTable();
MyDA.Fill(table);

BindingSource bSource = new BindingSource();
bSource.DataSource = table;

this.dataGridView1.DataSource = bSource;
DataGridViewColumn column = dataGridView1.Columns[2];
column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;

//dataGridView1.DataBindings.Add("Image", mbsPrimario, "PICFIELD", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged);

mcon.Close();

我用它来解码图片和成功

ID   Name    PIC
1    Leo     Image
2    Hello   Image

但我不知道如何获取每个字符串图像，解码它然后插回数据源。

Answer 1

显示字符串到图像的方式是这样的，

class MyClass {}
struct MyStruct {}

let newStruct = typeFromName("MyStruct").init()
let newClass = typeFromName("MyClass").init()

如何从mysql数据库向datagridview显示图像
