如何将DevExpress gridControl中RepositoryItemPictureEdit格式的图像保存到数据库中

// 1. 获取RepositoryItemPictureEdit中的图像数据
byte[] imageBytes = null;
if (repositoryItemPictureEdit.GetPictureEditValue() != null)
{
    Image image = (Image)repositoryItemPictureEdit.GetPictureEditValue();
    using (MemoryStream ms = new MemoryStream())
    {
        image.Save(ms, ImageFormat.Jpeg); // 将图像保存为字节数组
        imageBytes = ms.ToArray();
    }
}

// 2. 连接数据库
using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    
    // 3. 创建数据库表（如果尚未创建）
    string createTableQuery = "CREATE TABLE IF NOT EXISTS Images (Id INT IDENTITY(1,1) PRIMARY KEY, ImageData VARBINARY(MAX));";
    using (SqlCommand createTableCommand = new SqlCommand(createTableQuery, connection))
    {
        createTableCommand.ExecuteNonQuery();
    }
    
    // 4. 插入图像数据到数据库中
    string insertQuery = "INSERT INTO Images (ImageData) VALUES (@ImageData);";
    using (SqlCommand insertCommand = new SqlCommand(insertQuery, connection))
    {
        insertCommand.Parameters.AddWithValue("@ImageData", imageBytes);
        insertCommand.ExecuteNonQuery();
    }
}
