BlobEncoder.MethodSignature 方法

定義

將方法簽章 Blob 編碼。

public System.Reflection.Metadata.Ecma335.MethodSignatureEncoder MethodSignature (System.Reflection.Metadata.SignatureCallingConvention convention = System.Reflection.Metadata.SignatureCallingConvention.Default, int genericParameterCount = 0, bool isInstanceMethod = false);
member this.MethodSignature : System.Reflection.Metadata.SignatureCallingConvention * int * bool -> System.Reflection.Metadata.Ecma335.MethodSignatureEncoder
Public Function MethodSignature (Optional convention As SignatureCallingConvention = System.Reflection.Metadata.SignatureCallingConvention.Default, Optional genericParameterCount As Integer = 0, Optional isInstanceMethod As Boolean = false) As MethodSignatureEncoder

參數

convention
SignatureCallingConvention

呼叫慣例。

genericParameterCount
Int32

泛型參數的數目。

isInstanceMethod
Boolean

若要編碼執行個體方法簽章,則為 true;若要編碼靜態方法簽章,則為 false

傳回

簽章其餘部分 (包括傳回值和參數) 的編碼器。

例外狀況

genericParameterCount 不在範圍 [0, 0xffff] 內。

範例

此範例示範如何編碼不同的方法簽章:

static BlobBuilder EncodeMethodSignatureParameterless()
{
    // void Method()
    var methodSignature = new BlobBuilder();

    new BlobEncoder(methodSignature).
        MethodSignature().
        Parameters(0, returnType => returnType.Void(), parameters => { });
    
    return methodSignature;
}

static BlobBuilder EncodeMethodSignaturePrimitiveTypes()
{
    // double Method(double x, double y)
    var methodSignature = new BlobBuilder();

    new BlobEncoder(methodSignature).
        MethodSignature().
        Parameters(2, returnType => returnType.Type().Double(),
        parameters => {
            parameters.AddParameter().Type().Double();
            parameters.AddParameter().Type().Double();
        });

    return methodSignature;
}

static BlobBuilder EncodeMethodSignatureClassType(MetadataBuilder metadataBuilder)
{
    // void Method(System.Threading.Thread x)
    var methodSignature = new BlobBuilder();
    
    AssemblyReferenceHandle mscorlibAssemblyRef = metadataBuilder.AddAssemblyReference(
        name: metadataBuilder.GetOrAddString("System.Threading.Thread"),
        version: new Version(4, 0, 0, 0),
        culture: default(StringHandle),
        publicKeyOrToken: default(BlobHandle),
        flags: default(AssemblyFlags),
        hashValue: default(BlobHandle));

    TypeReferenceHandle typeRef = metadataBuilder.AddTypeReference(
        mscorlibAssemblyRef,
        metadataBuilder.GetOrAddString("System.Threading"),
        metadataBuilder.GetOrAddString("Thread"));

    new BlobEncoder(methodSignature).
        MethodSignature().
        Parameters(1, returnType => returnType.Void(),
        parameters => {
            parameters.AddParameter().Type().Type(typeRef, false);
        });

    return methodSignature;
}

static BlobBuilder EncodeMethodSignatureModifiedTypes()
{
    // void Method(ref int x, int[] y)
    var methodSignature = new BlobBuilder();

    new BlobEncoder(methodSignature).
        MethodSignature().
        Parameters(2, returnType => returnType.Void(),
        parameters => {
            parameters.AddParameter().Type(isByRef: true).Int32();
            parameters.AddParameter().Type().SZArray().Int32();
        });

    return methodSignature;
}

public static BlobBuilder EncodeMethodSignatureGeneric()
{
    // void Method<T>(T x)
    var methodSignature = new BlobBuilder();

    new BlobEncoder(methodSignature).
        MethodSignature(genericParameterCount: 1).
        Parameters(1, returnType => returnType.Void(),
        parameters => {
            parameters.AddParameter().Type().GenericMethodTypeParameter(0);
        });

    return methodSignature;
}

備註

在 .NET 元數據中定義或參考方法時,會使用方法簽章 Blob。 如需發出方法定義的完整範例,請參閱 MetadataBuilder 類別備註。
