今天在用DicomFile.Open(Stream s)这个接口时,遇到一个异常: DicomIoException: Requested 132 bytes past end of fixed length stream.
具体原因我们看下源码就很清楚:
public bool Require(uint count, ByteSourceCallback callback, object state) {
lock (_lock) {
if ((_stream.Length - _stream.Position) >= count)
return true;
throw new DicomIoException("Requested {0} bytes past end of fixed length stream.", count);
}
}
当时的Stream的Position位于流末尾,即Length-Position等于0, 因此抛出这个异常。
解决办法很简单:
首先把Stream定位到DICOM的起始位置。
类似代码如下:
var stream = new MemoryStream();
using (var f = File.Open(@"1.2.156.112605.75006881735343.1369658682.4.4.1.dcm", FileMode.Open))
{
f.CopyTo(stream);
}
stream.Seek(0, SeekOrigin.Begin);
var df = Dicom.DicomFile.Open(stream);
