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
