怎么使用FlexPaper分页加载获得总页数

Answer 1

-I可以获得页面信息
另外
下面是C#的方法
public int GetPageCount(string pdfPath)
{
try
{
byte[] buffer = File.ReadAllBytes(pdfPath);

int length = buffer.Length;

if (buffer == null)

return -1;

if (buffer.Length <= 0)

return -1;

string pdfText = Encoding.Default.GetString(buffer);

System.Text.RegularExpressions.Regex rx1 = new System.Text.RegularExpressions.Regex(@"/Type\s*/Page[^s]");

System.Text.RegularExpressions.MatchCollection matches = rx1.Matches(pdfText);

return matches.Count;

}
catch (Exception ex)
{
throw ex;
}

}
