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.Autentication"; (defined in the reference of the
Project )
methodService = "MyMethod";

object wsMacro = objAssembly.CreateInstance(pathService);

Type wsType = wsMacro.GetType();
MethodInfo MethodWS = wsType.GetMethod(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.XmlScanner.ScanHexEntity()
System.Xml.XmlTextReader.ParseBeginTagExpandCharEn tities() +1036
System.Xml.XmlTextReader.Read() +216
System.Xml.XmlReader.ReadElementString()

at System.Xml.XmlReader.ReadElementString()\r\n at
Microsoft.Xml.Serialization.GeneratedAssembly.XmlS erializationReader1.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
