Exemplos
O exemplo de código seguinte demonstra o uso contextual do EmitCalli método para chamar um método de tipo não gerido externo à classe dinâmica.
MethodBuilder myMthdBuilder = myTypeBuilder.DefineMethod("MyMethod",
MethodAttributes.Public,
returnType, mthdParamTypes);
// We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
// that it has a method "ToString" which returns a string.
MethodInfo unmanagedMthdMI = Type.GetType("LegacyNumber").GetMethod("ToString");
ILGenerator myMthdIL = myMthdBuilder.GetILGenerator();
// Code to emit various IL opcodes here ...
// Load a reference to the specific object instance onto the stack.
myMthdIL.Emit(OpCodes.Ldc_I4, addrOfLegacyNumberObject);
myMthdIL.Emit(OpCodes.Ldobj, Type.GetType("LegacyNumber"));
// Make the call to the unmanaged type method, telling it that the method is
// the member of a specific instance, to expect a string
// as a return value, and that there are no explicit parameters.
myMthdIL.EmitCalli(OpCodes.Calli,
System.Runtime.InteropServices.CallingConvention.ThisCall,
typeof(string),
new Type[] {});
// More IL code emission here ...
Dim myMthdBuilder As MethodBuilder = myTypeBuilder.DefineMethod("MyMethod", _
MethodAttributes.Public, _
returnType, mthdParamTypes)
' We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
' that it has a method "ToString" which returns a string.
Dim unmanagedMthdMI As MethodInfo = Type.GetType("LegacyNumber").GetMethod("ToString")
Dim myMthdIL As ILGenerator = myMthdBuilder.GetILGenerator()
' Code to emit various IL opcodes here ...
' Load a reference to the specific object instance onto the stack.
myMthdIL.Emit(OpCodes.Ldc_I4, addrOfLegacyNumberObject)
myMthdIL.Emit(OpCodes.Ldobj, Type.GetType("LegacyNumber"))
' Make the call to the unmanaged type method, telling it that the method is
' the member of a specific instance, to expect a string
' as a return value, and that there are no explicit parameters.
myMthdIL.EmitCalli(OpCodes.Calli, System.Runtime.InteropServices.CallingConvention.ThisCall, _
GetType(String), New Type() {})
' More IL code emission here ...

Parâmetros
- callingConvention
- CallingConventions
A convenção de chamadas geridas a ser utilizada.
- parameterTypes
- Type[]
Os tipos dos argumentos necessários para a instrução.
- optionalParameterTypes
- Type[]
Os tipos dos argumentos opcionais para varargs chamadas.
Exceções
optionalParameterTypes não nullé , mas callingConvention não inclui a VarArgs bandeira.
Observações
Usa EmitCalli para colocar uma Calli instrução no stream. Não utilize Emit.
Se optionalParameterTypes especificar argumentos opcionais, callingConvention deve incluir a CallingConventions.VarArgs bandeira.
