执行批量复制时出现以下错误。
System.InvalidOperationException
The given value of type String from the data source cannot be converted to
type decimal of the specified target column.
我使用以下代码。
DataTable empTable = DataTemplate.GetEmployees();
DataRow row;
for (int i = 0; i < gv.Rows.Count;i++ )
{
row = empTable.NewRow();
string empName = gv.DataKeys[i].Values[0].ToString(); //first key
string hourSalary = gv.DataKeys[i].Values[1].ToString(); //second key
row["Emp_Name"] = empName;
row["Hour_Salary"] = Convert.ToDecimal(hourSalary);
row["Advance_amount"] = Convert.ToDecimal(0);
row["Created_Date"] = Convert.ToDateTime(System.DateTime.Now.ToString());
row["Created_By"] = Convert.ToInt64(1);
row["Is_Deleted"] = Convert.ToInt64(0);
empTable.Rows.Add(row);
}
InsertintoEmployees(empTable, "Employee");
上述字段的我的 SQL 数据类型是:
Emp_Name nvarchar(50) ,
Hour_Salary numeric(18, 2),
Advance_amount numeric(18, 2),
Created_Date datetime,
Created_By numeric(18, 0),
Is_Deleted numeric(18, 0)
我不知道我做错了什么。
