# Assign Value

This action can be used to assign the value of the evaluated expression (output) to the specified variable (input).

## **Properties**

![](/files/-MfgG_C-0e3QJTU7DW3H)

### **Input**

* **Input**: the variable to be assigned a new value of the evaluated expression.

### **Output**

* **Output**: the C# expression which will be evaluated. Complex expressions are allowed and functions from different namespaces can be used, as long as the full namespace is provided.

{% hint style="info" %}
The expression must not end with a semicolon as the interpreter escapes the string automatically.
{% endhint %}

{% hint style="info" %}
The following expression is valid:

DateTime.Now\.ToString(“HH-mm-ss”)

Also, note that the full namespace for the C# DateTime.Now the structure is used without the System namespace. Other less used classes or functions should use this naming convention.
{% endhint %}

### **Misc**

* **Display Name**: action display name in your implementation project
* **Wait Before**: number milliseconds robot to wait before executing the action.
* **Wait After:** number milliseconds robot to wait until moving to the next action.
* **Abort on Error**: True/False
* **Retry Times**: Specifies the number of times to retry an action if it doesn't end successfully. Default value 0 (no retry); Use -1 if you want to retry indefinitely. 

## **Use Case**

### **Potential Use Cases**

* Assign the URL of an application to be automated
* Assign the current invoice to be processed
* Assign to a variable the value of the current exchange rate taken from xe.com using Http REST Request.
