C# Excel导出超出65536行报错 Invalid row number (65536) outside allowable range (0..65535)

　　c# excel导出超出65536行报错 invalid row number (65536) outside allowable range (0..65535)

一：报错

invalid row number (65536) outside allowable range (0..65535)

原因：excel 03的限制就是65536行，超过行数就报错

二：解决方案-创建多个sheet

public string export(list<record> list, string f) {
string name = "";
hssfworkbook book = new hssfworkbook();
hssfsheet sheet = book.createsheet("stud");
// 声明一行
hssfrow row = sheet.createrow(0);
row = sheet.createrow(0);
row.createcell(0).setcellvalue("身份");
row.createcell(1).setcellvalue("信用");
int index = 0;//记录额外创建的sheet数量
for (int i = 0; i < list.size(); i++) {
if ((i + 1) % 65535 == 0) {
sheet = book.createsheet("stud" + index);
row = sheet.createrow(0);
row.createcell(0).setcellvalue("身份");
row.createcell(1).setcellvalue("信用");
index++;
}
row = sheet.createrow((i + 1) - (index * 65535));
// 第四步，创建单元格，并设置值
row.createcell((short) 0).setcellvalue(list.get(i).getstr("info"));
row.createcell((short) 1).setcellvalue(list.get(i).getstr("score"));
}
// 第六步，将文件存到指定位置
string filename = "";
try {
filename = f + "/download/导出.xls";
name = "导出.xls";
file file = new file(filename);
if (file.exists()) {
file.delete();
}
fileoutputstream fout = new fileoutputstream(filename);
book.write(fout);
fout.close();
} catch (exception e) {
e.printstacktrace();
}
return name;

}
