示例1: CreateNewMethod
private static SyntaxNode CreateNewMethod(
SyntaxGenerator generator, IMethodSymbol methodSymbol, int parameterIndex, Compilation compilation, INamedTypeSymbol uriType)
{
// create original parameter decl
var originalParameter = generator.ParameterDeclaration(methodSymbol.Parameters[parameterIndex]);
// replace original parameter type to System.Uri
var newParameter = generator.ReplaceNode(originalParameter, generator.GetType(originalParameter), generator.TypeExpression(uriType));
// create original method decl
var original = generator.MethodDeclaration(methodSymbol, generator.DefaultMethodBody(compilation));
// get parameters from original method decl
var originalParameters = generator.GetParameters(original);
// replace one of parameter to new one
return generator.ReplaceNode(original, originalParameters[parameterIndex], newParameter);
