C# 按部门拆分excel文件

按照所属部门不同将excel文件拆分成多个文件

string excel_path = @"G:\zhyue\backup\2018-08-01 读取腾讯邮箱接口-获取一个月内未接收到外部邮件且已离职的邮箱\address_biz (4).csv";
string save_path = @"G:\zhyue\backup\2018-08-01 读取腾讯邮箱接口-获取一个月内未接收到外部邮件且已离职的邮箱\拆分excel\";

//解决中文乱码
TxtLoadOptions lo = new TxtLoadOptions();
lo.Encoding = Encoding.Default;

//打开excel文件
Workbook curr_wb = File.Exists(excel_path) ? new Workbook(excel_path, lo) : new Workbook();
//打开第一个sheet
Worksheet sheet_first = curr_wb.Worksheets[];
Cells Cells = sheet_first.Cells;
//一共多少行数据
int rows = sheet_first.Cells.MaxDataRow + ;

//不同的部门名称集合
List<string> lst_departments = new List<string>();
//excel的数据集合
List<UserInfo> lst_excel = new List<UserInfo>();

for (int i = ; i < rows; i++)
{//从第二行开始
    lst_excel.Add(new UserInfo()
    {
        username = Cells[i, ].StringValue,
        email = Cells[i, ].StringValue,
        othername = Cells[i, ].StringValue,
        department = Cells[i, ].StringValue,
        contact = Cells[i, ].StringValue,
        phone = Cells[i, ].StringValue,
        sex = Cells[i, ].StringValue,
        position = Cells[i, ].StringValue,
        number = Cells[i, ].StringValue,
        bindwechat = Cells[i, ].StringValue,
        remark = Cells[i, ].StringValue
    });
}

//遍历不同的部门
lst_excel.Select(x => x.department).Distinct().ToList().ForEach(x =>
{
    Workbook wb1 = new Workbook();
    Worksheet sheet_first1 = wb1.Worksheets[];
    Cells Cells1 = sheet_first1.Cells;

    //新生成的excel文件名
    string[] str_arr1 = x.Split('/');
    string department_new_name = str_arr1.Length >  ? x.Substring(x.IndexOf('/') + ).Replace('/', '-') : x;

    Cells1[, ].PutValue("姓名");
    Cells1[, ].PutValue("电子邮件");
    Cells1[, ].PutValue("别名");
    Cells1[, ].PutValue("所属部门");
    Cells1[, ].PutValue("联系电话");
    Cells1[, ].PutValue("手机");
    Cells1[, ].PutValue("性别");
    Cells1[, ].PutValue("职务");
    Cells1[, ].PutValue("编号");
    Cells1[, ].PutValue("绑定微信");
    Cells1[, ].PutValue("备注");
    int i = ;//当前行数 从第2行开始
    //查找excel中的这些部门并遍历
    lst_excel.Where(y => y.department == x).ToList().ForEach(y =>
    {
        Cells1[i, ].PutValue(y.username);
        Cells1[i, ].PutValue(y.email);
        Cells1[i, ].PutValue(y.othername);
        Cells1[i, ].PutValue(y.department);
        Cells1[i, ].PutValue(y.contact);
        Cells1[i, ].PutValue(y.phone);
        Cells1[i, ].PutValue(y.sex);
        Cells1[i, ].PutValue(y.position);
        Cells1[i, ].PutValue(y.number);
        Cells1[i, ].PutValue(y.bindwechat);
        Cells1[i, ].PutValue(y.remark);

        i++;
    });

    wb1.Save(save_path + department_new_name + ".xlsx", SaveFormat.Xlsx);
});

结果：

每个excel里面都只有自己部门的数据
