示例1: Build
public Expression Build(IEventTraceOperand operand, ParameterExpression eventRecordReader, ParameterExpression eventRecordWriter, ParameterExpression eventMetadataTable, ParameterExpression runtimeMetadata)
{
var eventMetadata = Expression.Parameter(typeof(EventMetadata));
var properties = Expression.Parameter(typeof(PropertyMetadata[]));
var variables = new List<ParameterExpression>
{
eventMetadata,
properties
};
var expGenerator = new ExpressionGenerator(eventRecordReader, eventRecordWriter, properties);
var list = new List<Expression>
{
Expression.Assign(eventMetadata, Expression.ArrayAccess(eventMetadataTable, Expression.Constant(operand.EventMetadataTableIndex))),
Expression.Assign(properties, Expression.PropertyOrField(eventMetadata, "Properties")),
eventRecordWriter.Call("WriteEventBegin", eventMetadata, runtimeMetadata),
expGenerator.CodeGenerate(operand.EventPropertyOperands),
