# minArraySize

> The smallest number of elements in the array across all target objects. (Read Only)

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.3/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public int minArraySize { get; }
```

### Remarks

If the SerializedObject contains multiple objects, this property returns the smallest number of elements.  Unlike [SerializedProperty.arraySize](/engine/6000.3/script-reference/unityeditor/serializedproperty/arraysize.md) the minimum size is returned even if it is larger than [SerializedObject.maxArraySizeForMultiEditing](/engine/6000.3/script-reference/unityeditor/serializedobject/maxarraysizeformultiediting.md).  In that case SerializedObject.maxArraySizeForMultiEditing could be increased to permit access to the array contents.

When the SerializedObject contains only a single object, this property behaves in the same way as [SerializedProperty.arraySize](/engine/6000.3/script-reference/unityeditor/serializedproperty/arraysize.md) and returns the true array size.

### Examples

```csharp
using UnityEditor;
using UnityEngine;

public class MinArraySizeExample : ScriptableObject
{
    public int[] m_data;

    [MenuItem("Example/SerializedProperty MinArraySize Example")]
    static void TestMethod()
    {
        const int largeArraySize = 100; // Larger than the default maxArraySizeForMultiEditing value of 64

        MinArraySizeExample obj1 = ScriptableObject.CreateInstance<MinArraySizeExample>();
        obj1.m_data = new int[largeArraySize];

        for (int i = 0; i < largeArraySize; i++)
            obj1.m_data[i] = i;

        // Second object with its own copy of the large array
        MinArraySizeExample obj2 = ScriptableObject.CreateInstance<MinArraySizeExample>();
        obj2.m_data = obj1.m_data;

        // Create serialized object for manipulating both objects
        SerializedObject serializedObject = new SerializedObject(new Object[] { obj1, obj2 });
        SerializedProperty property = serializedObject.FindProperty("m_data");

        // arraySize returns 0 but minArraySize returns largeArraySize
        Debug.LogFormat("Array Size: {0}\nMin Array Size: {1}\nMax Array Size: {2}",
            property.arraySize, property.minArraySize, serializedObject.maxArraySizeForMultiEditing);

        // Any call to GetArrayElementAtIndex() at this point would fail

        // Extend the max permitted array size
        serializedObject.maxArraySizeForMultiEditing = property.minArraySize;

        // Now arraySize returns largeArraySize, and the elements can be retrieved
        Debug.LogFormat("New Array Size: {0}, Last element: {1}", property.arraySize, property.GetArrayElementAtIndex(largeArraySize - 1).intValue);
    }
}
