ModuleBuilder.DefineInitializedData Method

Defines an initialized data field in the .sdata section of the portable executable (PE) file.

Namespace:  System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

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

Parameters

name
Type: System.String

The name used to refer to the data. name cannot contain embedded nulls.

data
Type: System.Byte[]

The binary large object (BLOB) of data.

attributes
Type: System.Reflection.FieldAttributes

The attributes for the field. The default is Static.

Return Value

Type: System.Reflection.Emit.FieldBuilder
A field to reference the data.

ExceptionCondition
ArgumentException

The length of name is zero.

-or-

The size of data is less than or equal to zero or greater than or equal to 0x3f0000.

ArgumentNullException

name or data is null.

InvalidOperationException

CreateGlobalFunctions has been previously called.

Static is automatically included in attributes.

The data defined by this method is not created until the CreateGlobalFunctions method is called.

NoteNote

Starting with the .NET Framework 2.0 Service Pack 1, this member no longer requires ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag. (See Security Issues in Reflection Emit.) To use this functionality, your application should target the .NET Framework 3.5 or later.

The following example uses the DefineInitializedData method to define an initialized data field in the .sdata section of the portable executable (PE) file.

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();
