网上一般说是没有限制 直到 内存溢出

我反编译了Hashtable.cs

其一个构造函数如下

public Hashtable(int capacity, float loadFactor)        {            if (capacity < 0)            {                throw new ArgumentOutOfRangeException("capacity", Environment.GetResourceString("ArgumentOutOfRange_NeedNonNegNum"));            }            if ((loadFactor < 0.1f) || (loadFactor > 1f))            {                throw new ArgumentOutOfRangeException("loadFactor", Environment.GetResourceString("ArgumentOutOfRange_HashtableLoadFactor", new object[] { 0.1, 1 }));            }            this.loadFactor = 0.72f * loadFactor;            double num = ((float) capacity) / this.loadFactor;            if (num > 2147483647)            {                throw new ArgumentException(Environment.GetResourceString("Arg_HTCapacityOverflow"));            }            int num2 = (num > 11) ? HashHelpers.GetPrime((int) num) : 11;            this.buckets = new bucket[num2];            this.loadsize = (int) (this.loadFactor * num2);            this.isWriterInProgress = false;        }

 

 

可以看出capacity <0.72*2147483647*loadFactor （其中loadFactor 在0.1到1之间）

默认的loadFactor 为1f

故一般情况下 capacity < 1546188225.84
