ListRules与 S Amazon DK 或命令行工具配合使用

列出某事件总线的所有规则。

    /// List the rules on an event bus.
    /// </summary>
    /// <param name="eventBusArn">The optional ARN of the event bus. If empty, uses the default event bus.</param>
    /// <returns>The list of rules.</returns>

        {
            EventBusName = eventBusArn
        };
        // Get all of the pages of rules.

此示例显示该区域的所有 CloudWatch 事件规则：

aws events list-rules

显示以特定字符串开头 CloudWatch 的事件规则列表。

此示例显示该区域中名称以 “Daily” 开头的所有 CloudWatch 事件规则：

aws events list-rules --name-prefix "Daily"

使用规则名称启用规则。
