"Insufficie nt state to deserialize the object. More information is needed." AppDomain Load

[Sean McKaharay]

I am using the code below and I am getting this error:
"Insufficie nt state to deserialize the object. More information is needed."
Has anyone seen this? It is working with other dll's but not on a certain
one. Can some help?


private void LoadAssembly(st ring DllLocationDire ctory, string
applicationName , bool shadowCopyFiles , string friendlyName, string dllName,
string className)
{
AppDomainSetup setup = new AppDomainSetup( );
setup.Applicati onBase = DllLocationDire ctory;
setup.Applicati onName = applicationName ;
setup.ShadowCop yFiles = shadowCopyFiles .ToString();
setup.ShadowCop yDirectories = DllLocationDire ctory;

this._AppDomain = AppDomain.Creat eDomain(friendl yName, null, setup);

SetAppDomainPol icy(_AppDomain) ;

byte[] AssemblyBtyes = this.LoadAssemb lyBytes(DllLoca tionDirectory +
dllName);
Assembly asm = this._AppDomain .Load(AssemblyB tyes);
this._ClassLoad ed = asm.CreateInsta nce(className);
}

private byte[] LoadAssemblyByt es(string filename)
{
FileStream fin = new FileStream(file name, FileMode.Open,F ileAccess.Read) ;
byte[] bin = new byte[16384];
long rdlen = 0;
long total= fin.Length;
int len;
MemoryStream memStream = new MemoryStream((i nt)total);
rdlen = 0;
while(rdlen < total)
{
len = fin.Read(bin, 0, 16384);
memStream.Write (bin, 0, len);
rdlen = rdlen + len;
}
// done with input file
fin.Close();
return memStream.ToArr ay();
}

This error is caused because it can't load a particular assembly. Make sure
the assembly is findable, for example by placing it into the GAC or the
program directory of the .exe which is doing the deserialization .

Fran,

It has to be deeper than that. When I try another dll it works.

Sean,

Can you give all the Exception information (call stack, message, etc,
etc), as well as the line it occurs on?
