示例1: GenerateCode
/// <summary>
/// Generates CIL for the statement.
/// </summary>
/// <param name="generator"> The generator to output the CIL to. </param>
/// <param name="optimizationInfo"> Information about any optimizations that should be performed. </param>
public override void GenerateCode(ILGenerator generator, OptimizationInfo optimizationInfo)
{
// Generate code for the start of the statement.
var statementLocals = new StatementLocals();
GenerateStartOfStatement(generator, optimizationInfo, statementLocals);
// Emit an unconditional branch.
// Note: the continue statement might be branching from inside a try { } or finally { }
// block to outside. EmitLongJump() handles this.
optimizationInfo.EmitLongJump(generator, optimizationInfo.GetContinueTarget(this.Label));
// Generate code for the end of the statement.
GenerateEndOfStatement(generator, optimizationInfo, statementLocals);
