FromType Method

Determines a VarType for a given .NET type.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<CanBeNullAttribute()>
Public Shared Function FromType( _
   ByVal type As Type _
) As VarType

'Usage
 
Dim type As Type
Dim value As VarType
 
value = VarType.FromType(type)

[CanBeNull()]
public static VarType FromType( 
   Type type
)

[CanBeNull()]
public:
static VarType^ FromType( 
   Type^ type
)

Parameters

type: The .NET type.
The value of this parameter can be null (Nothing in Visual Basic).

Return Value

Returns a VarType that corresponds to the input argument; null if there is no correspondence.

Because there is an implicit conversion from VarType to System.Int32 and VarTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the return value in place of an integer (System.Int32) (representing the numerical value of the COM VARTYPE), or in place a VarTypes enumeration value. When the implicit conversion operators are not supported (such as with Python.NET), you can use the ToInt32 or ToVarTypes static method instead.

This method can return null (Nothing in Visual Basic).

Remarks

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
