我目前正在我的程序结束，但我进入了一个我没有经验的部分。我已经能够通过其他方法将 PDF 转换为 Base64，但根据我的说明，这些方法是不允许的给定的。我已经在下面发布了我的代码，希望有人可以让我朝着正确的方向开始。我也不知道如何放入这些卷，所以任何帮助都会很棒！包含的是 Get Binaries 和它读取的 IO 类。

private static List<Binary> GetBinaries()
{
return new List<Binary>
{
new Binary
{
//hardcoded but need to call from fileUpload1
BinaryBase64Object = IO.ReadFromFile(@"..\..\EFACTS eRecord Technical Specification.pdf"), **<-- How do I get this to read from fileupload1**
BinaryID = "BIN1234", //hardcoded
BinarySizeValue = 56443, //hardcoded
FileName = " test.my.pdf", //hardcoded
PageRange = "23-89", //hardcoded
NoOfPages = 14, //hardcoded
TotalVolumes = 1, //hardcoded
Volume = 1 //hardcoded
}
};
