ModuleBuilder.DefineInitializedData 方法

项目
08/17/2007

在可移植可执行 (PE) 文件的 .sdata 部分定义已初始化的数据字段。

**命名空间:**System.Reflection.Emit
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Function DefineInitializedData ( _
    name As String, _
    data As Byte(), _
    attributes As FieldAttributes _
) As FieldBuilder
用法
Dim instance As ModuleBuilder
Dim name As String
Dim data As Byte()
Dim attributes As FieldAttributes
Dim returnValue As FieldBuilder

returnValue = instance.DefineInitializedData(name, data, attributes)

public FieldBuilder DefineInitializedData (
    string name,
    byte[] data,
    FieldAttributes attributes
)

public:
FieldBuilder^ DefineInitializedData (
    String^ name, 
    array<unsigned char>^ data, 
    FieldAttributes attributes
)

public FieldBuilder DefineInitializedData (
    String name, 
    byte[] data, 
    FieldAttributes attributes
)

public function DefineInitializedData (
    name : String, 
    data : byte[], 
    attributes : FieldAttributes
) : FieldBuilder

参数

name
用于引用数据的名称。name 不能包含嵌入的空值。

data
数据的 Blob。

attributes
该字段的属性。默认为 Static。

返回值

引用这些数据的字段。

异常

异常类型	条件
ArgumentException	name 的长度为零。 - 或 - data 的大小小于等于零，或者大于等于 0x3f0000。
ArgumentNullException	name 或 data 为空引用（在 Visual Basic 中为 Nothing）。
InvalidOperationException	以前调用过 CreateGlobalFunctions。

ArgumentException

name 的长度为零。

- 或 -

data 的大小小于等于零，或者大于等于 0x3f0000。

ArgumentNullException

name 或 data 为空引用（在 Visual Basic 中为 Nothing）。

InvalidOperationException

以前调用过 CreateGlobalFunctions。

备注

Static 自动包括在 attributes 中。

此方法定义的数据在调用 CreateGlobalFunctions 方法之后才被创建。

// Define the initialized data field in the.sdata section 
// of the PE file.
FieldBuilder myFieldBuilder = myModuleBuilder.DefineInitializedData(
    "MyField", new ubyte[] { 1, 0, 1 }, 
    FieldAttributes.Static | FieldAttributes.Public);
myModuleBuilder.CreateGlobalFunctions();
