.．.简而言之:

string[] arr = "This is a sentence".Split(new string[] { "is" }, StringSplitOptions.None);

string strData = "This is much easier"
int intDelimiterIndx = strData.IndexOf("is");
int intDelimiterLength = "is".Length;
str1 = strData.Substring(0, intDelimiterIndx);
str2 = strData.Substring(intDelimiterIndx + intDelimiterLength, strData.Length - (intDelimiterIndx + intDelimiterLength));

您可以使用string . replace()将所需的分割字符串替换为字符串中不存在的字符，然后使用string。在该字符上拆分以拆分结果字符串以获得相同的效果。

string[] arr = "This is a sentence".Split(new string[] { "is" }, StringSplitOptions.None);

根据这篇文章的现有回复，这简化了实现:)

namespace System
{
    public static class BaseTypesExtensions
    {
        /// <summary>
        /// Just a simple wrapper to simplify the process of splitting a string using another string as a separator
        /// </summary>
        /// <param name="s"></param>
        /// <param name="pattern"></param>
        /// <returns></returns>
        public static string[] Split(this string s, string separator)
        {
            return s.Split(new string[] { separator }, StringSplitOptions.None);
        }


    }
}

或者使用这个代码;(相同:new String[])

.Split(new[] { "Test Test" }, StringSplitOptions.None)
