Table Environment Variable via COM

I'm afraid, the ItcTableVariable interface is currently COM-incompatible, so you can't cast to it. You'll need to use a generic object-type variable for a table variable and access its properties and methods using reflection. Casting the Iterator property value to ItcTableVariableIterator should work fine though. Here's an example:

using System.Reflection;

...



object Table1 = tableVars["TheTableVariable"];



// Get the row and column count

int rowCount = (int) Table1.GetType().InvokeMember("RowCount", BindingFlags.GetProperty, null, Table1, null);

int colCount = (int) Table1.GetType().InvokeMember("ColumnCount", BindingFlags.GetProperty, null, Table1, null);

Console.WriteLine("Rows: {0}; columns: {1}", rowCount, colCount);



// Get the table iterator

ItcTableVariableIterator iterator = (ItcTableVariableIterator) Table1.GetType().InvokeMember("Iterator", BindingFlags.GetProperty, null, Table1, null);

while (!iterator.IsEOF())

{

  // Do something

  iterator.Next();

}

Or, if you use C# 4, you can use dynamic late binding. Something along the lines of:

dynamic Table1 = tableVars["TheTableVariable"];



var iterator = Table1.Iterator;

// -- or --

// ItcTableVariableIterator iterator = (ItcTableVariableIterator) Table1.Iterator;
