Problem during invoke remote Web Service

[franz1975]

Hi all,

I have developed an Library Application with ASP.NET 1.1.

In this environment i call Remote Web Service in this way :

*************** *************** *************** **********
where
pathService = "test.Autentica tion"; (defined in the reference of the
Project )
methodService = "MyMethod";

object wsMacro = objAssembly.Cre ateInstance(pat hService);

Type wsType = wsMacro.GetType ();
MethodInfo MethodWS = wsType.GetMetho d(methodService );
objectWS[0] = param1;
objectWS[1] = param2;
objectWS[2] = param3;
objectWS[3] = param4;
objectWS[4] = param5;

result = MethodWS.Invoke (wsMacro, objectWS);

When i get result from remote WS less then 15KB all wokrs fine, i can
read and manipulate result XML,

but when result is more than 16KB i got this error:

System.Xml.XmlS canner.ScanHexE ntity()
System.Xml.XmlT extReader.Parse BeginTagExpandC harEntities() +1036
System.Xml.XmlT extReader.Read( ) +216
System.Xml.XmlR eader.ReadEleme ntString()

at System.Xml.XmlR eader.ReadEleme ntString()\r\n at
Microsoft.Xml.S erialization.Ge neratedAssembly .XmlSerializati onReader1.Read3 _eseguiResponse ()" string

It seams like parsing XML due to error reading from remote web service.

Why this error happen only for big request?

How can I solve it?

Thanks in advances

Franz
