Syntax
Public Overridable Sub EmitCalli ( _
opcode As OpCode, _
callingConvention As CallingConventions, _
returnType As Type, _
parameterTypes As Type(), _
optionalParameterTypes As Type() _
)
public virtual void EmitCalli(
OpCode opcode,
CallingConventions callingConvention,
Type returnType,
Type[] parameterTypes,
Type[] optionalParameterTypes
)
Parameters
- opcode
Type: System.Reflection.Emit..::.OpCode

- callingConvention
Type: System.Reflection..::.CallingConventions
The managed calling convention to be used.
- returnType
Type: System..::.Type
The Type of the result.

| InvalidOperationException | optionalParameterTypes is not nullNothingnullptra null reference (Nothing in Visual Basic), but callingConvention does not include the CallingConventions..::.VarArgs flag. |
Remarks
Use EmitCalli to put a Calli instruction onto the stream. Do not use Emit.
If optionalParameterTypes specifies optional arguments, callingConvention must include the CallingConventions..::.VarArgs flag.
