使用对象数组时，表没有主键

Question

byte[] movieCover = null;
FileStream movieStream = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read);
BinaryReader movieReader = new BinaryReader(movieStream);
movieCover = movieReader.ReadBytes((int)movieStream.Length);
var movieTable = MovieTable();
var Starwars = new object[2];
Starwars[0] = "Star Wars: Episode I - The Phantom Menace";
Starwars[1] = 1999; //Also tried using a string
var sw = movieTable.Rows.Find(Starwars);

sw仍为null我的表格如下

CREATE TABLE [dbo].[Movie] (
    [Name]         NVARCHAR (50) NOT NULL,
    [Release Year] INT           NOT NULL,
    [Producer]     NVARCHAR (50) NULL,
    [Rating]       INT           NULL,
    [Covor]        IMAGE         NULL,
    [Description]  TEXT          NULL,
    PRIMARY KEY CLUSTERED ([Name] ASC, [Release Year] ASC)
);

我自己努力解决这个问题但是我已经被困了好几天了！我想做的就是手动添加图片！

终于解决了。要拉出主键，请按here

在调用Fill方法之前，需要将DataAdapter.MissingSchemaAction设置为MissingSchemaAction.AddWithKey。

DataAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
