04 Members
ParseDateTime(
String)Parsing the dat value from the expression text, if any exception happend, a null date value will returned. (空字符串会返回空的日期)
Parameters
| Name | Type | Description |
|---|---|---|
s | String | - |
CTypeDynamic(
IEnumerable(Of String), Type)Parse the target string value collection as a new array in the given element target type
Parameters
| Name | Type | Description |
|---|---|---|
expression | IEnumerable(Of String) | A collection of object data in string value |
target | Type | The element type |
CTypeDynamic(
String, Type)Converts a string expression which was input from the console or script file to the specified type.
Remarks
If all failure, then will try Conversion.CTypeDynamic(). (请注意，函数只是转换最基本的数据类型，转换错误会返回空值，空字符串也会返回空值)
Parameters
| Name | Type | Description |
|---|---|---|
expression | String | The string expression to convert. |
target | Type | The type to which to convert the object. |
Returns
An object whose type at run time is the requested target type.
CTypeDynamic(
IEnumerable, Type)the given type value should be the target array element type.
Parameters
| Name | Type | Description |
|---|---|---|
array | IEnumerable | - |
type | Type | - |
CTypeDynamic``1(
String, ``0)Converts a string expression which was input from the console or script file to the specified type.
Remarks
(请注意，函数只是转换最基本的数据类型，转换错误会返回空值，空字符串也会返回空值)
Type Parameters
| Name | Description |
|---|---|
T | The type to which to convert the object. |
Parameters
| Name | Type | Description |
|---|---|---|
expr | String | The string expression to convert. |
Returns
An object whose type at run time is the requested target type.
DefaultTextParser``1
默认的字符串解析方法为InputHandler.CTypeDynamic()脚本值动态转换函数
Type Parameters
| Name | Description |
|---|---|
T |
IsPrimitive(
Type)Does this type can be cast from the String type?
Remarks
(目标类型能否由字符串转换过来??)
Parameters
| Name | Type | Description |
|---|---|---|
targetType | Type | - |
Dynamics updates the capability of function InputHandler.CTypeDynamic(), InputHandler.CTypeDynamic() and InputHandler.IsPrimitive()
Parameters
| Name | Type | Description |
|---|---|---|
briefName | String | - |
stringConvertType | Type | - |
cast | LoadObject | - |
GetType(
String, Boolean)Get .NET clr Type definition info from its name. (类型获取失败会返回空值，大小写不敏感)
Parameters
| Name | Type | Description |
|---|---|---|
name | String | Case insensitive.(类型的名称简写) |
ObjectGeneric | Boolean | 是否出错的时候返回 |
GetType(Value(Of String),
Boolean)Get .NET Type definition info from its name. (类型获取失败会返回空值，大小写不敏感)
Parameters
| Name | Type | Description |
|---|---|---|
name | Value(Of String) | Case insensitive.(类型的名称简写) |
ObjectGeneric | Boolean | 是否出错的时候返回 |
Convertible(
Type, Type)Does the inputtype type can be cast to type DefType. (主要为了方便减少脚本编程模块的代码)
Parameters
| Name | Type | Description |
|---|---|---|
inputType | Type | - |
DefType | Type | - |
ToString(
Object, String, Boolean)NumberConversionRoutines.CStrSafe(), 出现错误的时候总是会返回空字符串的，
注意：
- 对于一些基础的数据类型例如
Int32,Int64等则是以json序列化来构建字符串值， - 对于Byte数组则是被编码为base64字符串
Parameters
| Name | Type | Description |
|---|---|---|
obj | Object | - |
originToStringAsNothing | String | Result of |
CastArray``1(
Object)The parameter obj should implements a IEnumerable interface on the type. and then DirectCast object to target type.
Type Parameters
