Namespace: Microsoft.VisualBasic
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
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. |
| 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. |
| IsNumeric | Returns a Boolean value indicating whether an expression can be evaluated as a number. |
| 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. |
| QBColor | Returns an Integer value representing the RGB color code corresponding to the specified color number. |
| RGB | Returns an Integer value representing an RGB color value from a set of red, green and blue color components. |
| SystemTypeName | Returns a String value containing the system data type name of a variable. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TypeName | Returns a String value containing data-type information about a variable. |
| 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. |
| VbTypeName | Returns a String value containing the Visual Basic data type name 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.
