GetValueOrDefault
Retrieves the value of the current System.Nullable`1 object, or the object's default value.
Returns
The value of the System.Nullable1.Value property if the System.Nullable1.HasValue property is true; otherwise, the default value of the current System.Nullable1 object. The type of the default value is the type argument of the current System.Nullable1 object, and the value of the default value consists solely of binary zeroes.
GetValueOrDefault(
`0)Retrieves the value of the current System.Nullable`1 object, or the specified default value.
Parameters
| Name | Type | Description |
|---|---|---|
defaultValue | `0 | A value to return if the System.Nullable`1.HasValue property is false. |
Returns
The value of the System.Nullable1.Value property if the System.Nullable1.HasValue property is true; otherwise, the defaultValue parameter.
Equals(
Object)Indicates whether the current System.Nullable`1 object is equal to a specified object.
Parameters
| Name | Type | Description |
|---|---|---|
other | Object | An object. |
Returns
true if the other parameter is equal to the current System.Nullable1 object; otherwise, false. This table describes how equality is defined for the compared values: Return ValueDescriptiontrueThe System.Nullable1.HasValue property is false, and the other parameter is null. That is, two null values are equal by definition.-or-The System.Nullable1.HasValue property is true, and the value returned by the System.Nullable1.Value property is equal to the other parameter.falseThe System.Nullable1.HasValue property for the current System.Nullable1 structure is true, and the other parameter is null.-or-The System.Nullable1.HasValue property for the current System.Nullable1 structure is false, and the other parameter is not null.-or-The System.Nullable1.HasValue property for the current System.Nullable1 structure is true, and the value returned by the System.Nullable`1.Value property is not equal to the other parameter.
Equals(
`0)Value equals of Value.Value
Parameters
| Name | Type | Description |
|---|---|---|
other | `0 | - |
#ctor(
`0)Creates an reference value object with the specific object value
Parameters
| Name | Type | Description |
|---|---|---|
value | `0 | - |
#ctor
Value is Nothing
IsNothing
Is the Value.Value is nothing.
ToString
Display Value.Value ToString() function value.
GetJson
Get json string of the Value.Value.
Default
Create a new reference value with the default value of its underlying type, which is Nothing for reference type and zero for value type.
op_UnaryPlus(Value(Of `0))
Gets the Value.Value property value.
Parameters
| Name | Type | Description |
|---|---|---|
x | Value(Of `0) | - |
op_Equality(Value(Of `0),
`0)Inline value assignment: Dim s As String = Value(Of String) = var
Parameters
| Name | Type | Description |
|---|---|---|
value | Value(Of `0) | - |
o | `0 | - |
op_Equality(
`0, Value(Of `0))value equals?
Parameters
| Name | Type | Description |
|---|---|---|
o | `0 | - |
value | Value(Of `0) | - |
op_Like(Value(Of `0),
Type)Type match operator, this may consider inherits of base type and interface implementation.
Remarks
Unlike this operation its behavior, the Variant type its type match operator is a type exactly match operation.
Parameters
| Name | Type | Description |
|---|---|---|
o | Value(Of `0) | - |
type | Type | - |
HasValue
Gets a value indicating whether the current System.Nullable`1 object has a valid value of its underlying type.
Returns
true if the current System.Nullable1 object has a value; false if the current System.Nullable1 object has no value.
Index(
Object)Get data from Value.Value through its index method
Parameters
| Name | Type | Description |
|---|---|---|
key | Object | - |
Value
The object value with a specific type define.
