当我运行代码时，我遇到了这个错误，我怎么能解决这个问题呢？
未处理的类型异常 发生'System.Data.SqlServerCe.SqlCeException' System.Data.SqlServerCe.dll c＃
当我按添加记录按钮添加记录时，会出现此错误 紧凑的本地数据库中的字段。
答案 0 :(得分：1)
如果名称包含空格，则必须将名称括在方括号中。
string sql ="
INSERT INTO Empoyee_GI(Name,[Father Name], Birthdate, Address, City, Zone, Province,
[Cell Number], Email, [Employement Status], Hire Date,
[Renewal Date], Location, Position, BPS, Department, Gender,
[Maritial Status], CNIC, [Employement Number])
VALUES(...);";
SqlCeCommand cmd = new SqlCeCommand(sql,con);
请注意，您还应该使用React Router Documentation来避免sql注入！
