如何将集合转换为字符串变量？ [英] How to get collection into string variable ?

问题描述

我有一个LINQ集合。我想从集合中获取所有值并设置为字符串变量。



我的方案是 - >



Foreach（SalesPlan.Riders中的var riderId）



{



string str = 101,102,103; //这是riderId来自salePlan.riders



//这个str将从集合中填充，var riderId

Hi,

I have a LINQ collection.I want to take all values from collection and set into string variable.

My scenario is-->

Foreach(var riderId in SalesPlan.Riders)

{

string str= 101,102,103; //This is riderId coming from salePlan.riders

// This str will fill from collection, var riderId

}

推荐答案

尝试

Try

Foreach(var riderId in SalesPlan.Riders)

{

string str += riderId + ","; //This is riderId coming from salePlan.riders

// This str will fill from collection, var riderId

}
str = str.substring(0, riderid.Length-1);

如果需要，可以在字符串值之间放置逗号或任何其他分隔符。

You can put in a comma or any other separator between the string values if you want to.

可以使用StringBuilder。

you can use StringBuilder.

StringBuilder builder = new StringBuilder();
foreach(var riderId in SalesPlan.Riders)
{
   builder.Append(riderId);
   //bulider.AppendLine(riderId.ToStirng());

}
console.writeline(bulider);

我认为这有助于
