我似乎无法在asp.net中显示保存在ms access数据库中的图像

// 建立与数据库的连接
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=YourDatabase.accdb";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
    connection.Open();

    // 执行SQL查询，检索保存的图像数据
    string query = "SELECT ImageData FROM YourTable WHERE ID = @ID";
    using (OleDbCommand command = new OleDbCommand(query, connection))
    {
        command.Parameters.AddWithValue("@ID", yourImageID);
        byte[] imageData = (byte[])command.ExecuteScalar();

        // 将二进制数据转换为Base64编码的字符串
        string base64Image = Convert.ToBase64String(imageData);

        // 在网页上显示图像
        ImageControl.ImageUrl = "data:image/jpeg;base64," + base64Image;
    }
}
