Divide the number of records by 100. Whenever you processed so much records you increment progress by one. 将记录数除以100。每当处理这么多记录时，进度就会增加一。

Example: You have 1000 records. 示例：您有1000条记录。 1000/100 = 10. After 10 records you increment the progress-bar's Value property by one. 1000/100 =10。在10条记录之后，将进度条的Value属性增加1。

Use double as intermediate data type if you have a large number of records. 如果您有大量记录，请使用double作为中间数据类型。

Adjust for rounding errors and off-by-one errors. 调整四舍五入误差和一合一误差。

Decide if you increment "progress" at the start of your processing or after and of processing. 确定在处理开始时还是处理之后和处理中递增“进度”。

Divide the 100 by Number of records. 用100除以记录数。 this is your Step for progressBar, if the number of records are 1000 then it will be 100/1000 = step 这是您的progressBar步骤，如果记录数为1000，则它将为100/1000 = step
