使用 StreamWriter 将 headers 添加到 CSV 输出文件中
Adding headers into CSV output file using StreamWriter
我正在尝试将 headers 添加到 CSV 文件中,作为 headers 我希望在 WriteLine
.
中使用变量名称
这是我的代码:
using (StreamWriter file = new StreamWriter(fs))
{
for (int s = 0; s < pr.Length; ++s)
{
string[] UsersIDS = new string[] {""};
UsersIDS = db.GetUsersList(pr[s].ProjectID);
file.WriteLine(
pr[s].ProjectID + '"' + ',' +
'"' + pr[s].ProjectTitle + '"' + ',' +
pr[s].PublishStatus + '"' + ',' +
UsersIDS.Length);
}
}
只是普通的 WriteLine
和常量字符串似乎就是你想要的(除非你想通过反射或其他方式获取列名):
using (StreamWriter file = new StreamWriter(fs))
{
file.WriteLine( "ProjectID,ProjectTitle,PublishStatus,UsersIDS_Length");
for (int index = 0; index < pr.Length; index++)
{
var usersIds = db.GetUsersList(pr[s].ProjectID);
file.WriteLine("{0},\"{1}\",{2},{3}",
pr[s].ProjectID, pr[s].ProjectTitle,
pr[s].PublishStatus, usersIds.Length);
}
}
(听起来你还想在标题周围加上引号……其余的引号看起来不平衡)。
我建议你做以下修改
using (StreamWriter file = new StreamWriter(fs))
{
file.WriteLine("ProjectID, ProjectTitle,PublishStatus,Length");
for (int s = 0; s < pr.Length; ++s)
{
string[] UsersIDS = new string[] {""};
UsersIDS = db.GetUsersList(pr[s].ProjectID);
file.WriteLine( pr[s].ProjectID + '"' + ',' + '"' + pr[s].ProjectTitle + '"' + ',' + pr[s].PublishStatus + '"' + ',' + UsersIDS.Length);
}//end of for
