The Information type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Erl | Returns an integer indicating the line number of the last executed statement. Read-only. |
![]() ![]() | Err | Contains information about run-time errors. |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | IsArray | Returns a Boolean value indicating whether a variable points to an array. |
![]() ![]() | IsDate | Returns a Boolean value indicating whether an expression represents a valid Date value. |
![]() ![]() | IsDBNull | Returns a Boolean value indicating whether an expression evaluates to the System.DBNull class. |
![]() ![]() | IsError | Returns a Boolean value indicating whether an expression is an exception type. |
![]() ![]() | IsNothing | Returns a Boolean value indicating whether an expression has no object assigned to it. |
![]() ![]() | IsReference | Returns a Boolean value indicating whether an expression evaluates to a reference type. |
![]() ![]() | LBound | Returns the lowest available subscript for the indicated dimension of an array. |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() ![]() | UBound | Returns the highest available subscript for the indicated dimension of an array. |
![]() ![]() | VarType | Returns an Integer value containing the data type classification of a variable. |
The following example uses the VbTypeName function to return data type names for several variables.
Dim sysDateName As String = "System.DateTime" Dim sysShortName As String = "Int16" Dim sysBadName As String = "Nonsense" Dim testVbName As String testVbName = VbTypeName(sysDateName) ' Returns "Date". testVbName = VbTypeName(sysShortName) ' Returns "Short". testVbName = VbTypeName(sysBadName) ' Returns Nothing.
