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             {
                throw new ArgumentOutOfRangeException("capacity", Environment.GetResourceString("ArgumentOutOfRange_NeedNonNegNum"));
            }
            if ((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 默认的loadFactor 为1f
故一般情况下 capacity
