數據集將不會更新圖像數據庫

Question

我試圖將一個圖像插入SQL Server數據庫，它進入數據集，但是當save方法被調用時，SQL Server不會更改。

public void AddImage(OpenFileDialog openFileDialog1, List<Movie> movieList) 
{ 
    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 Starwars = new object[2]; 
    Starwars[0] = "Star Wars: Episode I - The Phantom Menace"; 
    Starwars[1] = "1999"; 
    var found = _movieSet.Tables["Movie"].Rows.Find(Starwars); 

    if (found != null) 
    { 
     found.SetField("Cover", movieCover); 
     var movieListFound = movieList.Find(x => x.Name == Starwars[0]); 
    } 
    else 
     MessageBox.Show("Movie Not Found"); 
} 

的保存方法

public void Save() 
{ 
    var movieConnection = new SqlConnection(); 
    try 
    { 
     movieConnection = new SqlConnection(Properties.Settings.Default.moviesConnectionString); 
     movieConnection.Open(); 
     _movieAdapter.Update(_movieSet, "Movie"); 
     movieConnection.Close();     
     } 
     catch (Exception e) 
     { 
     MessageBox.Show(e.Message); 
     } 
     finally 
     { 
      movieConnection.Dispose(); 
     } 
} 

添加新行工作，但沒有更新任何類型的變化對實際數據集時的保存方法被調用，不只是形象，但如果我更改表數據可視化器在調試數據。

又一次我回答我的問題，一天後，希望我有更好的反應，但我想我的信息必須不是最好什麼的。

我需要在Addimage方法中調用Save（）方法。

public void AddImage(OpenFileDialog openFileDialog1, List<Movie> movieList) 
{ 
    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 Starwars = new object[2]; 
    Starwars[0] = "Star Wars: Episode I - The Phantom Menace"; 
    Starwars[1] = 1999; 
    var found = MovieTable().Rows.Find(Starwars); 
    if (found != null) 
    { 
     found["Cover"] = movieCover; 
     var movieListFound = movieList.Find(x => x.Name == Starwars[0]); 
    } 
    else 
     MessageBox.Show("Movie Not Found"); 
    Save(); 

}
