ModuleBuilder.DefineInitializedData(String, Byte[], FieldAttributes) 方法

定義

命名空間:

System.Reflection.Emit

組件:

System.Reflection.Emit.dll

來源:

ModuleBuilder.cs

在可攜式執行檔 (PE) 的 .sdata 區段中定義初始化的資料欄位。

public:
 System::Reflection::Emit::FieldBuilder ^ DefineInitializedData(System::String ^ name, cli::array <System::Byte> ^ data, System::Reflection::FieldAttributes attributes);

public System.Reflection.Emit.FieldBuilder DefineInitializedData (string name, byte[] data, System.Reflection.FieldAttributes attributes);

member this.DefineInitializedData : string * byte[] * System.Reflection.FieldAttributes -> System.Reflection.Emit.FieldBuilder

Public Function DefineInitializedData (name As String, data As Byte(), attributes As FieldAttributes) As FieldBuilder

參數

name

String

用來參考資料的名稱。 name 不能包含內嵌的 null。

data

Byte[]

資料的二進位大型物件 (BLOB)。

attributes

FieldAttributes

欄位的屬性。 預設為 Static。

傳回

FieldBuilder

要參考資料的欄位。

例外狀況

ArgumentException

name 的長度為零。

-或-

data 的大小是小於等於零，或大於等於 0x3f0000。

ArgumentNullException

name 或 data 為 null。

InvalidOperationException

之前已呼叫過 CreateGlobalFunctions()。

範例

下列範例會 DefineInitializedData 使用 方法，在可攜式可執行檔 (PE) 檔案的 區段中定義初始化的數據欄位 .sdata 。

AppDomain^ currentDomain;
AssemblyName^ myAssemblyName;

// Get the current application domain for the current thread.
currentDomain = AppDomain::CurrentDomain;
myAssemblyName = gcnew AssemblyName;
myAssemblyName->Name = "TempAssembly";

// Define a dynamic assembly in the 'currentDomain'.
myAssemblyBuilder =
   currentDomain->DefineDynamicAssembly(
      myAssemblyName, AssemblyBuilderAccess::Run );

// Define a dynamic module in "TempAssembly" assembly.
myModuleBuilder = myAssemblyBuilder->DefineDynamicModule( "TempModule" );

// Define the initialized data field in the .sdata section of the PE file.
array<Byte>^ temp0 = {01,00,01};
FieldBuilder^ myFieldBuilder =
   myModuleBuilder->DefineInitializedData( "MyField", temp0,
      (FieldAttributes)(FieldAttributes::Static | FieldAttributes::Public) );
myModuleBuilder->CreateGlobalFunctions();

AppDomain currentDomain;
AssemblyName myAssemblyName;

// Get the current application domain for the current thread.
currentDomain = AppDomain.CurrentDomain;
myAssemblyName = new AssemblyName();
myAssemblyName.Name = "TempAssembly";

// Define a dynamic assembly in the 'currentDomain'.
myAssemblyBuilder =
   currentDomain.DefineDynamicAssembly
               (myAssemblyName, AssemblyBuilderAccess.Run);

// Define a dynamic module in "TempAssembly" assembly.
myModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule");

// Define the initialized data field in the .sdata section of the PE file.
FieldBuilder myFieldBuilder =
    myModuleBuilder.DefineInitializedData("MyField",new byte[]{01,00,01},
               FieldAttributes.Static|FieldAttributes.Public);
 myModuleBuilder.CreateGlobalFunctions();

Dim currentDomain As AppDomain
Dim myAssemblyName As AssemblyName
' Get the current application domain for the current thread.
currentDomain = AppDomain.CurrentDomain
myAssemblyName = New AssemblyName()
myAssemblyName.Name = "TempAssembly"
' Define a dynamic assembly in the 'currentDomain'.
myAssemblyBuilder = _
      currentDomain.DefineDynamicAssembly(myAssemblyName, AssemblyBuilderAccess.Run)
' Define a dynamic module in "TempAssembly" assembly.
myModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule")
' Define the initialized data field in the .sdata section of the PE file.
Dim myFieldBuilder As FieldBuilder = _
      myModuleBuilder.DefineInitializedData("MyField", New Byte() {1, 0, 1}, _
      FieldAttributes.Static Or FieldAttributes.Public)
myModuleBuilder.CreateGlobalFunctions()

備註

Static 會自動包含在中 attributes。

在呼叫 方法之前 CreateGlobalFunctions ，不會建立這個方法所定義的數據。
