DynamicMethod.ReturnTypeCustomAttributes Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the custom attributes of the return type for the dynamic method.
Namespace: System.Reflection.Emit
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Overrides ReadOnly Property ReturnTypeCustomAttributes As ICustomAttributeProvider
public override ICustomAttributeProvider ReturnTypeCustomAttributes { get; }
Property Value
Type: System.Reflection.ICustomAttributeProvider
An ICustomAttributeProvider representing the custom attributes of the return type for the dynamic method.
Remarks
Custom attributes are not supported on the return type of a dynamic method, so the array of custom attributes returned by the GetCustomAttributes method is always empty.
Examples
The following code example shows how to display the custom attributes of the return type of a dynamic method. This code example is part of a larger example provided for the DynamicMethod class.
' ReturnTypeCustomAttributes returns an ICustomeAttributeProvider
' that can be used to enumerate the custom attributes of the
' return value. At present, there is no way to set such custom
' attributes, so the list is empty.
If hello.ReturnType Is GetType(System.Void) Then
outputBlock.Text &= "The method has no return type." & vbLf
Else
Dim caProvider As ICustomAttributeProvider = _
hello.ReturnTypeCustomAttributes
Dim returnAttributes() As Object = _
caProvider.GetCustomAttributes(True)
If returnAttributes.Length = 0 Then
outputBlock.Text &= "The return type has no custom attributes." & vbLf
Else
outputBlock.Text &= "The return type has the following custom attributes:" & vbLf
For Each attr As Object In returnAttributes
outputBlock.Text &= " " & attr.ToString() & vbLf
Next attr
End If
End If
// ReturnTypeCustomAttributes returns an ICustomeAttributeProvider
// that can be used to enumerate the custom attributes of the
// return value. At present, there is no way to set such custom
// attributes, so the list is empty.
if (hello.ReturnType == typeof(void))
{
outputBlock.Text += "The method has no return type." + "\n";
}
else
{
ICustomAttributeProvider caProvider = hello.ReturnTypeCustomAttributes;
object[] returnAttributes = caProvider.GetCustomAttributes(true);
if (returnAttributes.Length == 0)
{
outputBlock.Text += "The return type has no custom attributes." + "\n";
}
else
{
outputBlock.Text += "The return type has the following custom attributes:" + "\n";
foreach (object attr in returnAttributes)
{
outputBlock.Text += " " + attr.ToString() + "\n";
}
}
}
