示例
下面的代码示例演示如何使用此构造函数。
#using <System.dll>
#using <System.Xml.dll>
using namespace System;
using namespace System::CodeDom;
using namespace System::CodeDom::Compiler;
int main()
{
// Declare a new type called Class1.
CodeTypeDeclaration^ class1 = gcnew CodeTypeDeclaration("Class1");
// Declares a type constructor that calls a method.
CodeConstructor^ constructor1 = gcnew CodeConstructor();
constructor1->Attributes = MemberAttributes::Public;
class1->Members->Add(constructor1);
// Creates a method reference for dict.Init.
CodeMethodReferenceExpression^ methodRef1 =
gcnew CodeMethodReferenceExpression(
gcnew CodeVariableReferenceExpression("dict"),
"Init",
gcnew array<CodeTypeReference^> {
gcnew CodeTypeReference("System.Decimal"),
gcnew CodeTypeReference("System.Int32")});
// Invokes the dict.Init method from the constructor.
CodeMethodInvokeExpression^ invoke1 =
gcnew CodeMethodInvokeExpression(methodRef1, gcnew array<CodeParameterDeclarationExpression^> {});
constructor1->Statements->Add(invoke1);
// Create a C# code provider
CodeDomProvider^ provider = CodeDomProvider::CreateProvider("CSharp");
// Generate code and send the output to the console
provider->GenerateCodeFromType(class1, Console::Out, gcnew CodeGeneratorOptions());
}
// The CPP code generator produces the following source code for the preceeding example code:
//
//public class Class1 {

// public Class1() {
// dict.Init<decimal, int>();
// }
// }
