示例1: AdjustInitializerStack
static bool AdjustInitializerStack(List<ILExpression> initializerStack, ILExpression argument, ILVariable v, bool isCollection)
{
// Argument is of the form 'getter(getter(...(v)))'
// Unpack it into a list of getters:
List<ILExpression> getters = new List<ILExpression>();
while (argument.Code == ILCode.CallvirtGetter || argument.Code == ILCode.Ldfld) {
getters.Add(argument);
if (argument.Arguments.Count != 1)
return false;
argument = argument.Arguments[0];
}
// Ensure that the final argument is 'v'
if (!argument.MatchLdloc(v))
return false;
// Now compare the getters with those that are currently active on the initializer stack:
int i;
for (i = 1; i <= Math.Min(getters.Count, initializerStack.Count - 1); i++) {
ILExpression g1 = initializerStack[i].Arguments[0]; // getter stored in initializer
ILExpression g2 = getters[getters.Count - i]; // matching getter from argument
if (g1.Operand != g2.Operand) {
// operands differ, so we abort the comparison
break;
}
}
// Remove all initializers from the stack that were not matched with one from the argument:
initializerStack.RemoveRange(i, initializerStack.Count - i);
// Now create new initializers for the remaining arguments:
for (; i <= getters.Count; i++) {
ILExpression g = getters[getters.Count - i];
MemberReference mr = (MemberReference)g.Operand;
TypeReference returnType;
if (mr is FieldReference)
returnType = TypeAnalysis.GetFieldType((FieldReference)mr);
else
returnType = TypeAnalysis.SubstituteTypeArgs(((MethodReference)mr).ReturnType, mr);
ILExpression nestedInitializer = new ILExpression(
IsCollectionType(returnType) ? ILCode.InitCollection : ILCode.InitObject,

// can't add children to collection initializer
if (parentInitializer.Arguments.Count == 1) {
// convert empty collection initializer to object initializer
