How to set value by call variable name from string c#

Question

Now I'm new for c# development.

I have 100 data from Array and also have 100 variables.

How can I match 100 data with 100 variables?

for example

for(int count = 0 ; count < array.lenght ; count++)
{
    Var+count = array[count];
}

Something like this.

or you guy have another solution please help me. I don't want to do like

set Var1 to Var100 by hand.

More Information Actually I need to add the arrays values to text object in CrystalReport

For example if I want to add the value

 TextObject txtLot1 = (TextObject)report.ReportDefinition.Sections["Section4"].ReportObjects["txtLot1"];

 txtLot1.Text = Arrays[i]

something like this. so , I try to use dictionary but I don't think it will work.

You are having an array, Then why are you going for 100 separate variables? access the values using its index, like what you are doing for assignment(`array[count]`) — sujith karivelil, Mar 19 '18 at 12:11
If you need a specific key to retrieve a specific value, you should look at turning your array into a Dictionary — Ryan Wilson, Mar 19 '18 at 12:12
I'm honestly not quite sure what your use case is. C# does not allow you to arbitrarily create and reference variables at runtime with names that are not pre-determined. That's why arrays/lists/dictionaries/etc exist. — Yannick Meeus, Mar 19 '18 at 12:12

This is almost certainly an X/Y problem. What are you actually *trying to do* here? The code is the "how you're currently trying to do it", which is not quite the same thing (especially for X/Y) — Marc Gravell, Mar 19 '18 at 12:16

Here is an example of doing what you are asking for on the fly with a System.Collections.Generic.Dictionary, all keys in a dictionary must be unique, but since you are appending 1 to each key in your loop this will suffice:

Dictionary<string, int> myKeyValues = new Dictionary<string, int>();

for(int count = 0 ; count < array.length; count++)
{
    //Check to make sure our dictionary does not have key and if it doesn't add key
    if(!myKeyValues.ContainsKey("someKeyName" + count.ToString())
    {
         myKeyValues.Add("someKeyName" + count.ToString(), count);
    }
    else
    {
        //If we already have this key, overwrite, shouldn't happen as you are appending a new int value to key each iteration
        myKeyValues["someKeyName" + count.ToString()] = count;
    }
}
