示例1: EvaluateExpression

// internally, vsdebugger calls our EE with literal "0"
int intResult;
if (int.TryParse(expressionString, out intResult))

}
// At refresh, Expression Evaluator may re-evaluate locals/arguments.
// To speed up the process, locals/arguments are cached.
LocalInfo cachedLocalInfo = null;
if (this.cachedLocalInfos != null && this.cachedLocalInfos.TryGetValue(expressionString, out cachedLocalInfo))
{
return cachedLocalInfo;
}
Activity activity = activityInstance.Activity;

// a temporary context for EvaluateExpression
// We're not using the executor so it's ok that it's null
CodeActivityContext context = new CodeActivityContext(activityInstance, null);
object result;
try
