寫好了，以下是截圖和部分代碼，完整的源碼在附件中，如有問題歡迎追問。

核心代碼：

private?void?buttonGetInfo_Click(object?sender,?EventArgs?e)

{

var?address?=?this.textBoxAddress.Text.Trim();

var?provinceIndex?=?address.IndexOf("省",?StringComparison.InvariantCultureIgnoreCase);

var?cityIndex?=?address.IndexOf("市",?StringComparison.InvariantCultureIgnoreCase);

var?countyIndex?=?address.IndexOf("縣",?StringComparison.InvariantCultureIgnoreCase);

var?provinceStartIndex?=?0;

var?provinceLength?=?provinceIndex;

var?cityStartIndex?=?provinceIndex?+?1;

var?cityLength?=?cityIndex?-?cityStartIndex;

var?countyStartIndex?=?cityIndex?+?1;

var?countyLength?=?countyIndex?-?countyStartIndex;

var?province?=?address.Substring(provinceStartIndex,?provinceLength);

var?city?=?address.Substring(cityStartIndex,?cityLength);

var?county?=?address.Substring(countyStartIndex,?countyLength);

this.labelProvince.Text?=?province;

this.labelCity.Text?=?city;

this.labelCounty.Text?=?county;

}
